Re: [GRASS-user] interlis import

2011-03-11 Thread Andreas Neumann

Hi Patrick,

I wouldn't try to open Interlis files directly in GRASS. You are better 
off converting them to an intermediate format or database, e.g. 
spatialite, PostgreSQL, GML, etc. and work from there.


If you open the files directly, performance will be bad.

btw: Interlis consists of two files:
1. .ili file (contains the data model: topics, tables, columns, data 
types, domain lists, etc.)
2. .itf file (the raw data: geometry and attribute data).  - itf means 
interlis transfer format


You always need both files.

Here are one or two examples: http://gis.hsr.ch/wiki/HowTo_OGR2OGR

Good luck,
Andreas

Dear List,

does someone have experience in importing the topological format 
INTERLIS to GRASS?
It seems to need an .ili file, that will define polygons, lines and 
points, but I don't see how to integrate this one in the v.in.ogr 
command.


I managed to use ogr2ogr and tested conversion to shapefile. This one 
uses the java interpreter ili2c.jar. (see: 
http://www.gdal.org/ogr/drv_ili.html). It will only work if the .ili 
is intergrated as in the command:


ogr2ogr -f ESRI Shapefile shpdir 
/home/order/filename.itf,/home/order/description.ili


When I import the .itf to GRASS it will only create lines instead of 
areas. Same result for conversion with ogr2ogr mentioned above when 
the .ili is not integrated.


Any Feedback would be helpful.

Patrick

Re: [GRASS-user] Re: GRASS Promotion Team

2010-10-25 Thread Andreas Neumann
Hi,

I am just commenting on the software.

Inkscape is a vector graphics editor based on SVG (for single pages
currently), similar to Illustrator or CorelDraw (although those may also
support multipage documents).

Inkscape, does not, per se produce large files if you stay with text and
vector graphics. The files can only get large if you embed a lot of raster
graphics. Embedding raster files can result in large files.

Scribus is more a DTP software than a graphics editor, similar to InDesign.

LaTeX is an entirely different beast with it's own strengths, best suited
for writing scientific papers and articles. I don't think it is very well
suited to design posters.

For posters, flyers, clipart and vector graphics I would go with Inkscape,
for multipage brochures I would go with Scribus and for manuals I would go
with LaTeX.

Btw: Inkscape can be used to produce and edit vector graphics that can
later be embedded in Scribus (as SVG) and in LaTeX (I think best as PDF or
PNG, or maybe also SVG in more recent versions).

Hi,

I got news from the GDAL mailing list, where I posted a similar
question about that strange format I downloaded on the CCM  JRC web
page. It seems to be the new ArcGIS file geodatabase format introduced
by ESRI in ArcGIS 9.2, according to Jason Roberts and Frank Warmerdam.
The important thing here is that it is a different database format
(from .mdb or argis personal database), entirely proprietary which
cannot, as of september 2009, be read by any OGR driver. So we took
steps to contact the author/distributor of CCM data in order to have
the set distributed in another format. More on this to follow.

[GRASS-user] Re: [Qgis-user] Re: [OSGeo-Discuss] augmenting donations

2009-07-04 Thread Andreas Neumann

Hi all,

I would like to discuss the sponsoring issue a little bit. For GIS 
managers that are not in direct charge of their budgets but need to 
discuss/approve their budget with their bosses/supervisors, I can say that:


* It is relatively easy to raise money for development work of concrete 
features that are to be implemented - bosses usually see a direct value 
out of this - and they are already used to pay non-open-source 
corporations for their specific development efforts anyway
* it is harder to raise money for bug-fixing - managers are often used 
to pay subscription fees or support contracts to commercial vendors, but 
usually aren't used to paying money to fix bugs
* it is very hard to justify donations - as bosses usually don't 
understand the open-source model fully - and often don't see their 
responsibilities as a user of an open-source project


I am just trying to help you guys to understand how government agencies 
or companies often work (exceptions are always possible). It is 
important to educate managers regarding the open-source development 
model. They are just not used to it and at the first glimpse they can 
find it strange - even if it is to their advantage.


One may discuss if QGIS/GRASS (or other projects) could offer yearly 
support contracts. It may help to raise additional money in some cases. 
It is important to distinguish such contracts from their fully 
commercial counterparts. Customers shouldn't be forced into paying those 
fees/contracts - but they may fell better with paying them. Probably, 
such contracts, would have to be done by individual companies - or could 
the steering board coordinate such activities?


Many managers in government agencies don't want to be held responsible 
in case things go wrong - and in case of using open-source software they 
are fully responsible about their decisions, whereas with commercial 
software they can always blame their commercial vendor (even if the 
contracts are always in favor of the software vendor and includes very 
limited liability of the vendor). At least in Switzerland I know that 
many GIS managers are thinking this way. They often want to at least 
share their responsibility with an external company.


Just my two cents,

Andreas

Thanks for sharing the link to the thesis.

I would like to add that some of the drawbacks of GRASS can be 
compensated by using GRASS together with QGIS. There are ongoing efforts 
(mainly by Marco Hugentobler) in QGIS currently to improve the layout 
and printing tools. I think the integration of both programs looks 
promising and I hope that in the future the two projects will 
collaborate and integrate even more where GRASS provides all the 
numerous analysis and topological features, a good vector engine and 
commandline for automation; and QGIS concentrates on the Desktop GIS and 
easy to use GUIs.

I have been a long-time user of ESRI products, but I want to start my
own contract business and will not be able to afford the license for
ArcGIS/ArcInfo. So I recently set up a Linux box with GRASS installed,
but it has been over 10 years since I have used GRASS (it has probably

Does GRASS have the same analysis and display capabilities as ArcGIS? I

WMS is not limited to rasters. One can also serve the WMS results as 
SVG, which is a vector format. SVG is supported by Opera, Safari and 
Firefox.


However, there aren't many WMS that support SVG.

WMS servers symbolized maps, though, and not original vector geodata. To 
get unsymbolized original vector data, you'd choose a WFS service.

Re: [GRASS-user] Vector drawings in PDF - converting them

2008-01-17 Thread Andreas Neumann
ok, the problems are with the curves.

The ogr2ogr tool has a converter from Interlis to other ogrformats.
Interlis supports arcs (defined by three points). They also calculate new
vertices along the arcs to be compatible to other formats that don't
support curves. One can define how many

Every SVG viewer has code on how to display curves (arcs, quadratic and
cubic spline curves). But I don't know if you can dig up and work with
that code directly. Many of them probably forward their drawing commands
to underlying graphics libraries like Cairo, AGG, OpenVG, Java2D, etc.

As you said, you might also want to ask the Batik developers on the Batik
list. These people are usually friendly and often help where they can.

Andreas


 Andreas,

 Thanks for you comments.  I agree completely.

 The curves are definitely where the problem lies.  There would need to
 be a clever algorithm that converted them to polylines with some sort of
 configurable resolution.  However, my guess is the code used convert SVG
 to raster formats like TIF and PNG has to do something similar.

 I began looking into using the facilities in Batik to accomplish this.
 The PNGTranscoder looks to be a good place to start.  Haven't gotten
 very far in this past weekend when I began to look into it, no blatant
 roadblocks yet.

 Hi,

 SVG would be a great format for transforming non-GIS vector maps into a
 GIS format. But it is not so surprising that most GIS only export and
 don't import SVG. SVG is usually a presentation format, not a transfer
 format for GIS data. Also, SVG has a lot of features that can't be
 easily
 transfered to GIS - think about elliptical arcs, cubic and quadratic
 spline curves. Those would have to be transfered into the OGC geometry
 models, where support for curves is more or less in its infancy.

 A number of GIS software allows the export of SVG, not always in a very
 form, though: Postgis (ok), Grass (did not try that), Mapserver (haven't
 tried that), ESRI (crappy, they seem to have some sort of resolution
 for
 their vector export).

 But, I think it would be great to have svg support incorporated into the
 ogr tools. It would make sense, also since FME and other OS and
 commercial
 GIS support SVG.

 I have a TON of vector drawings available to me in PDF format that I'm
 georeferencing.  So far, I'm doing it by converting them to PNGs and
 using r.to.vect to massage them.  This is really tedious and the data
 isn't as clean as a straight vector conversion would be.  In
 Illustrator, I can see that all the vector math is there.  That is, the
 PDF isn't simply a wrapper around raster data.

 I've tried opening the PDFs in Illustrator and exporting them as DXFs,
 but Grass ignores a lot of the data when I do this...they look very
 different in Grass once imported.  I can export them as SVG from
 Illustrator, but surprisingly, there doesn't appear to be a single
 open-source tool available out there that converts SVG into some
 mainstream GIS file format.

 Does anyone have experience doing this type of conversion?  Pointers
 welcome.

I really recommend PostgreSQL/Postgis. It might be a little more complex
to use than Filemaker, but it is easier to use than Oracle or DB2. I
believe it is the most widely supported spatial database in Open Source
GIS, but also increasingly in the commercial world (ESRI 9.3 will support
it through ArcSDE). Also it has a lot more spatial functionality than
MySQL or DB2. Don't know about Oracle Spatial.

As for database administration I recommend the GUI admin tool pgadmin3,
which is very intuitive and cross-platform. It misses the form-part of
Filemaker, but other than that it is really easy to use.

 Hi folks,

 I have some questions as to which databases people are using with
 grass.  I currently use Filemaker for as a database, but could never
 get it to link to GRASS.  I was wondering if this problem has been
 resolved.  Otherwise, I am considering which database software would
 provide easy of use and still get the data I need ported to my GRASS
 GISs.  I contemplating Postgresql but it isn't all that intuitive.
 How are MySQL and SQLite Browser?

Re: [GRASS-user] v.in.ogr should support postgis schemas

2007-11-22 Thread Andreas Neumann
I agree that schema support is essential. In Postgis one cannot join
tables from different databases, but it works well across schemas. So in
practice, all data usually ends up in one big database, but organized in
schemas. So yes, please, I also would very much appreciate if v.in.ogr
would support schemas.

Thank you for considering this improvement.

 Since more than one year the ogr PostGIS driver supports PostGIS
 schemas. For good DB-Modelling schemas are very essential. Unfortunately
 the v.in.ogr command doesn't support PostGIS schemas till today. How are
 the plans to introduce PostGIS schema support for v.in.ogr?
