I'm agree, it's a wrong assumption based on SRS name similarity. In fact, ESRI:102164 shall be interpreted by gvSIG as EPSG:20790. Geodesically speaking, ESRI:102164 and EPSG:20790 are two different SRSs, even if they looks very similar, for two reasons: firstly they adopt different prime meridians (respectively Greenwich and Lisboa), secondly ESRI:102164 doesn't consider the transformation parameters towards WGS84 (like all ESRI SRSs and it was in the past for all prj). So gvSIG doesn't relate them correctly, because they're not equivalent in Geodesy. Operationally speaking, instead, because their projected coordinates are the same, the user could set EPSG:20790 manually at the moment, as Mario has well explained in the previous email. It's clear that projection file recognition in gvSIG could be further improved including also ESRI codes, but the transformation parameters would be missing in that case. So I think that ESRI codes should be remapped as EPSG ones in order to take full advantage of transformation parameters and avoid unwanted data shifts.

Hi Silvia,

Hi all,
alternatively, as stated in my first post, it's possible to use only one

zfield = "ID"
if layer != None:
# get the input layer path (2D)
datastore = layer.getDataStore()
inLayerPath = datastore.getFullName()
# get the output layer path (3D)
dirname = os.path.dirname(inLayerPath)
filename = os.path.basename(inLayerPath).split(".")[0]
# for instance, we use the same file extension of the input layer
# but it could be another OGR format (e.g. SpatiaLite)
extension = os.path.basename(inLayerPath).split(".")[1]
outLayerPath = os.path.join(dirname, filename + "_3D." + extension)
if extension.lower() == "shp":
format = "ESRI Shapefile"
#elif extension.lower() == "..."
# format = "..."
else:
print "Not implemented yet!"
ogr2ogr.main(["-f", format,
outLayerPath,

Hi Lizandra, gvSIG can be used for such task and many others, for sure! Firstly, you can download the available WorldClim variables by tile (in reference to your area of interest) and format (e.g. GeoTIFF) from the WorldClim website. Then you can calculate other variables of your interest combining them using the Raster Calculator available in the Processing toolbox.

Gary, the tolerance value is generally expressed in meters or degrees respectively in projected and geographic coordinate reference systems. Sometimes lines are not snapped together, so the tolerance can be a great help. Alternatively, if we don't want to alter the input geometries, we can also use one of the Dissolve geoprocesses.

Hi Gary, the best tool available in gvSIG in order to accomplish this task should be the "Join adjacent lines" geoprocess. You can find it in the Geoprocessing toolbox under the "Tools for line layers". It allows to join lines even if their start and end points are not coincident thanks to a tolerance. Hope this helps!

Hi Silvia, after you set the color table, you should also click on the "Save as default" button in the "Color table" window in order to save a Raster MetaFile (rmf) containing the color table to apply always. Then if you create a new project and add the same raster datastore, it will be loaded with the same color table saved before and store in the rmf file. Tested in build 2425 win x86_64 and it works.

Yes, at least in theory... It will depend by how the CRS extension will be refactorized and the economic resources. It's an historical lack of gvSIG that needs to be solved, if gvSIG wants to grant the full interoperability with other GIS applications.

Ciao Silvia, unfortunately it's a known bug [1]. Your workflow is the right one, but the coordinate conversions and transformations toward EPSG:3857 are not yet supported in the latest versions of gvSIG (e.g. 2.2), because libjni-proj4 is outdated. :( So, in the meanwhile we have to reproject our data elsewhere (e.g. GDAL/OGR). This issue should be fixed in gvSIG 2.3 using the official bindings of GDAL for Java, as gvSIG core developers can confirm. Stay tuned! ;) Antonio [1] https://redmine.gvsig.net/redmine/issues/2739 PS: For completeness, please report always what version and build of gvSIG you are using. -- Antonio Falciano http://www.linkedin.com/in/antoniofalciano ___ Gvsig_internacional mailing list Gvsig_internacional@listserv.gva.es To see the archives, edit your preferences or unsubscribe from this mailing list, please access this url: http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional
Re: [Gvsig_english] : manipulating coordinates within a shape-file
Hi all, the simplest way to divide each coordinate by 1000, i.e. apply a *scale* factor of 0.001, consists into using the Transform geoprocess. Hope this helps!

Re: [Gvsig_english] Update of EPSG Registry in gvSIG 2.1
Hi César, I've tried some new Italian EPSG codes and they're working fine. All the CRSs (and their related transformations) contained in the latest version of the EPSG Registry are now available, such as those of Argentina requested in [#2455]. However, some issues still persist: [#1371], [#2596] and [#2389]. In reference to the first two, I've commented the related tickets. Instead, the last one seems to occur with other transformations too and it should depend by how gvSIG (and GeoTools) manage the direction of transformations and not by the Registry, because each transformation is declared only once in the Registry itself, even if it's valid in both directions. In order to test it, simply overwrite the EPSG.sql contained in the org.gvsig.projection.app.jcrs extension (in the case of a fresh install) or in the gvSIG user folder with that contained in [1], as described in [#2306]. And then have fun with CRSs and transformations! :) The next challenge is to finally add the support of projection files (.prj), but this is another ...feature request! ;) After the deep refactoring of gvSIG 2.x, it should be an absolute must!

techniques contained

Finally, use the "Contour lines" tool in order to create the

Re: [Gvsig_english] Visibility analysis
Il 24/09/2013 11:48, Angus Jeffery ha scritto: Hello I am doing some visibility analysis work in gvSIG. I often use the grass r.cva process and various of the sextante visibility tools for standard viewsheds. I would like to work out how to do a 'reverse viewshed', whereby the output is a raster/heat map within a parcel of land, showing which areas are more or less visible from the surrounding area outside the parcel of land in the wider landscape. Does anyone have any ideas which tools to use and how to approach this most efficiently in gvSIG? Best regards Angus Hi Angus, more or less visible suggests me you are trying to compute the so called fuzzy viewshed, i. e. the degree of visibility between 0 and 1 of targets and vice versa. This kind of viewsheds are more sofisticated than binary ones, which only say if a target is visible or not. The logic consists into applying a fuzzy membership based on some physic law to visibility and finally multiply the resulting raster with the classical binary viewshed. Some years ago [1] I reproduced them with SEXTANTE models (if I remember well with SEXTANTE 0.6), but I'm not sure if all the tools involved in this model are quite stable to do this work at the moment.

Re: [Gvsig_english] Visibility analysis
Il 24/09/2013 13:26, Angus Jeffery ha scritto: Hi Antonio Thanks for your reply. Very interesting despite my lack of Italian and I can see some application for your research. However, it's not quite what I meant - what I want to try to do is work out which part of a defined site (I have a polygon) is least (or most) visible from the surrounding landscape within a defined radius (I have raster of elevation data). Any ideas? Hi Angus, I'd convert the polygon into a set of equispaced points using e.g. the SEXTANTE Create graticule tool (to be clipped). The distance to adopt should be the DEM cell size. Each point can be considered as a single target and then be used for the computation of a binary viewshed in order to understand from where it's visible within the search radius. The number of pixels of the binary viewshed whose value is equal to 1 (i.e. the sum of all the values within the search radius) will represent the score of each point. Higher is the score, more visible from different places the point will be. It could be calculated with the SEXTANTE Basic statistics tool. The complex part is that we have to iterate over all the points and for sure the best approach is to do it programmatically, e.g. with some BeanShell scripting under SEXTANTE or Bash/Python under GRASS GIS.

Strangely enough, when trying to add the WMS again, I get exactly the same error message I got from Sextante before, the one included in the log file. So basically now we know what leads to the error message, but how can we add WMS or other raster files to the view and still use sextante? Or ist it a known bug already? Hi all, I have just tried to open the SEXTANTE toolbox in gvSIG 1.12 with a WMS layer (visible or not) and I cannot reproduce the issue.

I must be unlucky as I have stumbled on many such errors and wasted quite a lot of time trying to work around various issues. Editing in this version caused data corruption over and over, on different shapefiles sourced from different locations. In the end, due to time constraints, I have reverted to using gvSIG v1.10 and using other open source applications (QGIS and GRASS) to complete what at best would be called basic spatial work. Personally, I think this version should be flagged as Beta as it is in no way stable enough to be released into a production environment. Hi Simon, IMHO these words explained well the situation: Also it has to be taken into account that the level of stability of this new version is not as high as we would have wished, considering it a final version in order to be used by the community in an official way, and mainly to tackle the new developments on it.

When selecting from alternative repositories from the drop down list associated with the third radio button. The radio button should be automatically selected once an alternative repository is selected. IMHO, when an installation mode different from Installation from URL is selected, the repositories drop-down list should not be active, just like the textbox related to Installation from file. 3. It is unclear if the various repositories are mirrors. Some basic feedback to the user on this screen would help people understand when any of these option should be used. I like the idea that the URLs list should be updated remotely in order to clean it regularly and eventually set the best possible option, like http://downloads.gvsig.org/download/gvsig-desktop/, as the first available. This sounds like a further feature request! ;) 4. The main category list should also include not installed I should add an update category too, because it's not always clear if you have installed the last version of something (e.g. Addons manager). 5. In the main category list you have simbology it should be symbology. I suspect this would also be a good spot for the symbol sets. IMHO Symbology category should contain all related plugins and symbols. Instead, Symbols type should be related to all symbol sets, as it is actually designed. I add something else to this useful list... 6. I'd leave the operating system column and let gvSIG to understand on which os is running. 7. When some critical bugs about (experimental or not) plugins are fixed, I'd update the repositories more frequently in order to allow and encourage the users to continue the tests.

Re: [Gvsig_english] raster limitations
Il 26/09/2012 16.25, Andre Pais ha scritto: Hi there. I´ve downloaded the latest gvSIG version, 1.12 final. I´ve installed it (activated GRASS and SAGA in the Sextante options) and used right away because I have an academic work which consists of developing a spacial analysis exercice using raster operations, first using ArcGIS and then I must replicate it using an opensource, in my case gvSIG. In the process, here are a few problems I´ve came up to: Hi Andre, 1 - Sextante doesn´t allow to create a DEM-TIN like I did using 3d Analyst of Arcmap; SAGA has a function called Shape to TIN but it doesn´t generates an output ; The first one is a known limitation of gvSIG and SEXTANTE, because they are not able to manage a 3D TIN at the moment, but this is not the only way to create DEM fortunately. The second one may depend by SAGA (and GRASS) bindings in SEXTANTE which are not stable yet and so not all SAGA modules work fine. 2 - I need to create a DEM in order to generate slope and aspect charts for my area of study. Since there isn´t an option to define a mask (like there is in Arcmap), I did a clip using the shape with altimetric information as input and the area of study as clipping layer. The result has the altimetric information for my area of study. Then I need to rasterize this result layer. So I went to Sextante and used Rasterize vector layer in order to convert it to raster format, having defined an appropriate cell size and the extent as my area of study ( in the hope that the result would have the form of my area of study). Then I did a void filling ( I´ve read this somewhere) to generate a proper DEM. But unfortunately the result is a rectangular DEM instead of being limited to my area of study (which by the way is the portuguese equivalent to an ayuntamiento) Why? This behavior is what we should expect. In fact, the result of Void filling doesn't take in count your mask because of its definition: it completes the information of one raster layer that has cells without data. The information to complete the cells without data is taken from the surrounding cells using interpolation methods. (Source: SEXTANTE help). So the mask should be applied after (and not before) the Void filling by multiplying them. 3 - There is an option in Sextante called Rasterize vector layer (for mask) but it doesn´t seem to do what i want. I have tried it and seems to work like a charm. Its result should be a mask with ones where there are vector geometries, otherwise zero. 4 - The GRASS function v.to.rast is to confusing and doesn´t work properly. It gives an error :Failed to import data into GRASS mapset; See my answer to the point 1. These are SEXTANTE bugs, I'm sorry. 5 - The reclassify function of sextante is a bit confusing as well. It requires a min value, a max value and a new value. For example, if i need to reclassify a slope chart, e.g, 5 classes (0-10%, 10-20%, 20-30%, 30-40% and 40%). I have put the min and max for the each class. Why do I need to write new values? Shouldn´t the program assume that? I´ve tried to write 1, 2, 3, 4 ,5 (to match the classes) but the output has 0 value in some pixels but there is no class 0. Why? Because it's not possible to write in the reclassified raster 0-10%, 10-20%, 20-30%, 30-40% and 40%, so let's say we need some aliases in order to do this task. AFAIK it works everywhere in this way. 6 - Why haven´t the programmers of the latest version improved the symbology options and visualization in rasters. It´s a pain having to work in black, grey and white and not be able to see the classes of a certain raster with different colors (with this being shown in the view) You can apply the color table you like, as Francisco suggested.

My slope classes are: 0 - 10; 10 - 20; 20 - 30; 30 - 40 e 40 so i would do this: 0|10|1 10|20|2 20|30|3 30|40|4 40|1000|5 which means that 0-10 slope class would be equal to 1, 10-20 slope class would be equal to 2 ...and so on. You can save these rows as CSV file and load it as LUT in the Reclassify tool by clicking on the Open button of the Fixed table dialog. By the way is it normal to have a max slope over 100%? Yes, I think so... Take a look at this: http://en.wikipedia.org/wiki/File:Grades_degrees.svg Consider that a percent slope of 100% means that the tan(alpha) is equal to 1, i.e. alpha is equal to 45 degree. ;) Cheers, Antonio -- Antonio Falciano http://www.linkedin.com/in/antoniofalciano ___ Gvsig_internacional mailing list Gvsig_internacional@listserv.gva.es To see the archives, edit your preferences or unsubscribe from this mailing list, please access this url: http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional

/ {{{

Re: [Gvsig_english] Set EPSG:4326 as default CRS for new views (gvSIG feature requests #753)
Hi all,
IMHO geographically speaking, EPSG:4326, i.e. a global CRS, is much
neutral than a national one, like EPSG:23030. We generally use WGS84 from
all countries! Furthermore, I often see how several (not only basic)
users adopt EPSG:23030 improperly, while using EPSG:4326 would have the
advantage to represent projected coordinates in degrees in the status
bar and so encouraging us to change the CRS of the view accordingly with
our geodata. Without talking about web services which use only WGS84
geographic coordinates...!
I'm agree with Ben about an initial agnostic CRS (for instance, useful
in local surveys), however if there's the need to initialize a CRS in
gvSIG, I think that EPSG:4326 is better, because covers the most part of
user needs and it represents the best possible compromise.
@Francisco: thanks for opening the ticket #779!
Cheers,
Antonio

I don't have a strong opinion on this, so i encourage people to
express themselves before make the change.
Anyway, i'm not sure, but i think that there are some places in the
code that 23030 is hardcoded, so it should be identified and changed.
This can have secondary effects, so i don't feel comfortable making
the change for 1.12.
I open a ticket for the 1.x branch.

Again, thanks for point this Antonio.
2012/6/13 Benjamin Duckebendu...@fastmail.fm:
I don't think there is any good default for a spatial
reference system. The only thing that makes sense IMHO
would be to allow users to work without any SRS at all
and to set one when/if they choose to.
Btw. you can set the default SRS for new views in
the program preferences, so whatever the gvSIG default
may be: it's easy to change it permanently.

Ben

Re: [Gvsig_english] bug in build 1411 gvSIG 1.12: NoSuchMethodError with Shortest path (org.gvsig.graph)
Hi Fran, thanks for your kind attention and amazing work. I take this opportunity to suggest two useful feature requests in reference to the Network Analysis extension: 1) adding a Save / Load barriers layer buttons (options) in the Route control panel (Network menu); 2) adding a Delete all option in the Network / Delete submenu (as first option possibly). They should be very easy to implement and save time in the analysis. Cheers, Antonio Il 12/06/2012 0.36, Francisco José Peñarrubia ha scritto: Hi Antonio.

3) wildcards are not allowed;

Re: [Gvsig_english] SLD grammar syntax
Archaic solution that works fine in gvSIG 1.12 devel too! ;) Although,
at least one among numerator and denominator has to be double.
So, instead of
[field]=0.5
we have to type
[field]=(1.0/2)
or
[field]=(1/2.0)

Re: [Gvsig_english] gvSIG 1.11: add consecutive numbers to selection?
Hi all, field expression is based on the values of the same row, however field calculator commands are Jython's functions. So it's possible to memorize a variable during field calculations using the advanced tab, for instance loading and evaluating the following script consecutiveN.py: #consecutiveN.py from javax.swing import JOptionPane def consecutiveN(): global index try: if rec() == 0: index = 0 else: index = index + 1 except: index = '' return index # Usage: consecutiveN() JOptionPane.showMessageDialog(None, 'Usage: consecutiveN()', consecutiveN, JOptionPane.INFORMATION_MESSAGE) Its usage is very simple. If the first record is not selected, the index will be 1-based and so consecutiveN() will do the trick, otherwise it will start from 0 and so consecutiveN()+1 would be necessary.

[Gvsig_english] Add transparency to all the symbols of a legend [1]
Hi all, here's two Jython scripts about legends of vector layers: http://ge.tt/9gxJWxA?c (Batch legend and Batch Transparency) In detail, the script Batch transparency allows to apply the transparency/opacity to all the classes of symbols of one or more vector layers at once, a common task that is very time consuming, as you all probably know by experience. I'm sure that it can be improved further because not all shape and symbols types are currently supported, however I was wondering if it could be a good starting point in order to have this feature in the official gvSIG versions.

I wish to write a specific expression as Python script, to be used in the Field Calculator (after starting an editing session). Reading through the Manual, I see that it is possible just saving this script in a Python file and uploading it from the appropriate box: Field Calculator Advanced tab. I've done it, also using some dummy script, but it doesn't work. Can anybody post some explicit example of using this feature? Iacopo, you have simply to define a Jython function which returns the result of your calculation, load it from the Advanced tab and finally use that function as the built-in functions of the Field Calculator. For instance, if we have a field containing the area expressed in square meters (e.g. SUP_M2) and we want to convert it in square kilometers, we can write: def m2tokm2(value): result=value/100 return result We save this script as conversion.py, load it from the Advanced tab and then we can use the Jython function writing in correspondence of a new field called e.g. SUP_KM2: m2tokm2([SUP_M2]) Finally, the field SUP_KM2 will be populated by area expressed in km^2. ciao Antonio -- Antonio Falciano http://www.linkedin.com/in/antoniofalciano ___ Gvsig_internacional mailing list Gvsig_internacional@listserv.gva.es To see the archives, edit your preferences or unsubscribe from this mailing list, please access this url: http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional

Please test it from here: http://dl.dropbox.com/u/2131623/com.iver.cit.gvsig.cad.zip (Remove the com.iver.cit.gvsig.cad folder in your gvSIG installation and use this) Notice also, in edition properties the option to active remove last vertex with the right button of the mouse.

But what can be done with snappers and follow geometry? If you have many layers where are able to snapped the system becomes really slow.
