[gdal-dev] PDF Driver projection support for Mercator_1SP Mercator_2SP

[Gane R]

Does the PDF driver support these projections

Here is such an example of file with projection
https://lists.osgeo.org/pipermail/gdal-dev/2016-September/045147.html

I see some fix applied for GeoTIFF https://trac.osgeo.org/gdal/ticket/5791

Any thoughts? for PDF driver or I am wrong they already exists in latest
GDAL

[gdal-dev] gdal-1.11.3 to gdal-2.3.1 compatibility

[Gane R]

Hi all,

Is gdal-1.11.3, opening vector data set, reading OGR features code
compatible with gdal-2.3.1 code or any major changes in accessing OGR
features ?

Thanks

[gdal-dev] OGR SYMBOL style format

[Gane R]

Hi,

I am trying to draw OGR features with style in a defined by a vrt file.
I want point features to be placed with my custom icon with the OGR Feature
style.
So I tried,
The following line works when I change the size parameter s:n
SYMBOL(c:#00FF,s:50px,id:ogr-sym-3);

The following line doesn't show any change in output image drawn size when
I change the size parameter s:n
SYMBOL(c:#00FF,s:50px,id:bus_stop.png);

The above line doesn't seem to have any change in the image resize on the
point locations. But, then I use the default "ogr-sym-3" I see a change in
the output,

Did I miss any style parameters or is there any way to have the image
resized before placing at the location of the point features?

Thanks

Hi all,

Is there any way to disable one or all OGR formats when building on Linux.
i.e.,
when using ./configure

Is there any way to disable certain raster formats when building on Linux

[gdal-dev] GDAL 2.2.4 with c++11

[Gane R]

Does the latest version of GDAL 2.2.4 can be compiled without c++11 support
or it is mandatory to compile with c++11.

Is there any possibility I can build with a compiler which doesn't support
c++11.

Can you point any relevant information on this?

Thanks

[gdal-dev] Page Selection in GeoPDF in GDAL utilizes like gdalwarp, gdal_translate

[Gane R]

I have a GeoPDF with Map on second page, first page is kind of foreword.

 Do We have any way in GDAL to say to GDAL API use page 2 of this GeoPDF
for gdal_translate or gdalwarp ?

[gdal-dev] PDF not oriented as expected

[Gane R]

I had a chance to work with prebuild gdal-2-1-3 bin, I tried to convert a
PDF to TIFF, with attached PDF, the PDF is not oriented to the north
rotation as expected on the TIFF.

I tried to work with source and found the angle dfRotation is reported as
zero. The resultant GeoTIFF output is not north oriented. Here is a link to
PDF

[gdal-dev] Build GDAL with PDFium

[Gane R]

Hi all,

I tried to Build GDAL with PDFium on linux, I succeeded it.
 I faced the following issue
F .text._ZN13CFDF_Document12CreateNewDocEv   00ac .hidden
CFDF_Document::CreateNewDoc() *got that fixed by changing standalone.gypi
removing -fvisibility=hidden*.

As an next step *I tried to Build GDAL with PDFium for android(cross
compile)* I succeed it.

But when I try to* load the GDAL's shared library libgdal.so.20 which is
dependent for my shared lib libread.so. *

I see unsatisfied link error unable to load symbols in libgdal.so.20
U _ZN13CFDF_Document12CreateNewDocEv
U _ZN13CPDF_Document15AddStandardFontEPKcP17CPDF_FontEncoding

But I see
 T _ZN13CPDF_Document15AddStandardFontEPKcP17CPDF_FontEncoding
 T _ZN13CPDF_Document12CreateNewDocEv
in
pdfium/out/Release/obj.target/fpdfapi/core/src/fpdfapi/fpdf_edit/fpdf_edit_doc.o
(also in libfpdfapi.a)

any suggestions on this issue or any one has worked on this will of great
help.

Re: [gdal-dev] Build PDFium with GDAL

[Gane R]

Hi all,
I am trying to build GDAL with PDFium

I have used the link to get build script for linux
https://github.com/rouault/pdfium/tree/build

only change in standalone.gypi was removal of -fvisibility=hidden in
standalone.gypi
I got a GDAL build with pdfium build was success,
But gdalinfo for a Geospatial PDF crashes
at version gdal-2.2.0

Has anybody tried to build GDAL with PDFium recently, or there was a change
in the PDFium source ?

[gdal-dev] Build PDFium with GDAL

[Gane R]

Hi all,
I am trying to build GDAL with PDFium

I saw the link
https://github.com/rouault/pdfium/tree/build

I tried to use the linux script and the pdfium static lib to build. *pdfium
build succeed.*

I have few Questions:

Q1: I see some 3rdpary dependency for PDFium, I don't see those LICENSES
included, does overall including the 3rparty dependency, PDFium library
comes to point like similar to MIT license ?.

Q2. Can we do a cross compile with for PDFium, or any one tried.

Q3. Has any one got an error like this (error message follows in next few
lines) ? or I have gone wrong in build steps.

I started to build GDAL gdal-2.2.0 with pdfium

[gdal-dev] Building GDAL on linux with minimal drivers

[Gane R]

Hi all,

I am looking for building gdal with minimal set of drivers like gdal with
geotiff, jpg, png and sqlite gpkg

so it should do basic warp geotiff and work with geopkg raster. I don't
need OGR part I need the core, alg and raster tif, gpkg, jpg and png alone
is enought.
the problem is I get a fat static lib. I want to reduce its size.

I tried to follow the post
https://trac.osgeo.org/gdal/wiki/BuildingOnUnixWithMinimizedDrivers It
seems it is old.

When I build i get error during building the apps like gdalinfo, gdalwarp


Any suggestions

my ogr/ogrsf_frmts/GNUmakefile  is
like

include ../../GDALmake.opt

SUBDIRS-yes:= \
generic rec shape

SUBDIRS-$(HAVE_DODS)+= dods
SUBDIRS-$(HAVE_DWGDIRECT) += dxfdwg
SUBDIRS-$(HAVE_FME)+= fme
SUBDIRS-$(HAVE_GRASS)+= grass
SUBDIRS-$(HAVE_IDB)+= idb

I get the following error

[gdal-dev] Build GDAL on iOS for iPhone

[Gane R]

Hi all,

I had a change to see the link
http://stackoverflow.com/questions/12643898/incorporating-gdal-ogr-into-an-ios-project-a-quick-guide

This was guiding to build with Xcode 4.0, the above link says that it
doesn't work with Xcode version above 4.0

I just wanted to build GDAL as static library for iPhone and use the OGR
library there in iPhone.

I modified the build script as shown here, build_gdal_ios_cus.sh

[gdal-dev] Build GDAL for android via NDK

[Gane R]

Hi all,

I saw a link for Building GDAL for android on linux

https://trac.osgeo.org/gdal/wiki/BuildingForAndroid

Is it updated ?, I tried to build on centOS, It took the android linux
compiler. The make resulted in a error. gdal 2.1.0

Is there any updated document or any one having personal experience in
building GDAL for android or any documentation that has worked will be of
great help.

[gdal-dev] Get a List of tiles source name from the gpkg_content

[Gane R]

I see the usage of the gdalinfo for the gpkg with multiple tile source as
Subdataset,
I also saw the source code of gdalinfo getting the subdataset





*Q1: Can I get a list of tiles source name (table_name) in gpkg_contents
data_type as tiles?Is there any API call*
*or only by the following code ?*

char **papszSubdatasets = GDALGetMetadata( hDataset, "SUBDATASETS" );
int nSubdatasets = CSLCount( papszSubdatasets );

char szKeyName[1024];
char *pszSubdatasetName;

snprintf( szKeyName, sizeof(szKeyName),
  "SUBDATASET_%d_NAME", psOptionsForBinary->nSubdataset
);
szKeyName[sizeof(szKeyName) - 1] = '\0';
pszSubdatasetName =
CPLStrdup( CSLFetchNameValue( papszSubdatasets, szKeyName )
);

Thanks

[Gane R]

thanks for your reply,

I see the subdatasets name in gdalinfo.

Q1:
However how do I know the name of a tile raster if the GPKG has only one
tile raster source,I want to get the name as in gpkg_contents table.

[gdal-dev] Creating a GeoPackage with multiple tile raster source in gdal 2.1.0

[Gane R]

Hi all,

I am using a pre-build version of gdal 2.1.0. I am able to create GeoTIFF
to GeoPackage using gdal_translate.

I see from the Geopackage specification I understand that Geopackage can
have multiple tile sources, If so

Q1: How to I add a tilesource to an exisiting geopackage from a GeoTIFF ?
any command line or any workflow sequence will be of great help.

Q2: If a geopackage has multiple Geopackage tile raster, If I wish to
convert any one to a geotiff how will I do ? Should I used OGR Select layer
or how ??

Thanks

[gdal-dev] Creating multiple zooms in MBTiles generation

[Gane R]

Hi,

I was working with gdal 2.1.0, I was trying to convert a geopackage raster
to mbtiles, I used GDALCreateCopy to convert the dataset to mbtiles.

On http://www.gdal.org/frmt_mbtiles.html

I saw an example to use gdal_translate and then to use gdaladdo to
overviews

Q1: I got only one level of zoom level in the mbtiles. Is there any
creation option to say to generate mbtiles from a to b zooms ? or I have to
do by build overviews ???


Q2: I tried to convert the Geopackage ERDC_Whitehorse_GeoPackage.gpkg size
111 MB in Web Mercator EPSG:3857 from the url

http://www.geopackage.org/#sampledata

(GeoPackage contains a raster tile pyramid that was created with free
imagery obtained from Geomatics Yukon and covers an approximately 30
square-kilometer area centered on the City of Whitehorse. It uses the Web
Mercator (EPSG:3857) coordinate reference system, 256x256 pixel tiles,
contains zoom levels 11-18, and is 110.8MB in size)



*The resulting mbtiles was to 621MB Is this due to default PNG zlevel
settings or any thing can be done on this ?*
Thanks

[gdal-dev] Using TILE_SCHEME option converting GeoTIFF to GeoPackage

[Gane R]

Hi all,

Here is a link to Geopackage sample name ERDC Whitehorse GeoPackage.gpkg
at
https://portal.opengeospatial.org/files/63156

I tried like this

gdal_translate.exe -of GPKG "sample.tif" "sample.gpkg" -co *TILING_SCHEME*
=PseudoTMS_GlobalMercator

I got only one zoom level in the output Geopackage, from the input GeoTIFF
here example sample.tif

*Q1:*
*I want to know how do I convert a GeoTIFF to below mention tile Schemes I
tried, correct If I am wrong.*
I have gdal 2.1.0 pre-built binary with to see with the latest version.

TILE_SCHEME

1 CUSTOM
2 GoogleCRS84Quad
3 GoogleMapsCompatible
4 InspireCRS84Quad
5 PseudoTMS_GlobalGeodetic
6 PseudoTMS_GlobalMercator


*I see there are 3 variations*
1. Tile Format: PNG, JPEG, WEBP
2. Tile Scheme:

   - CUSTOM
   - GoogleCRS84Quad
   - GoogleMapsCompatible
   - InspireCRS84Quad
   - PseudoTMS_GlobalGeodetic
   - PseudoTMS_GlobalMercator

3. Projection parameter at gpkg_contents srs_id : epsg code


*Q2:Is that an raster tile may be in other EPSG code other than 3857 and
4326 Not clear when reading the Geopackage specification and is it
implemented in GDAL ?*
Thanks

[1] Is is possible to get the progress 10...20... into a variable and [2]
is it possible to cancel the warp progress, say cancel the operation.

I saw the documentation and sample in JPEG CreateCopy, gdal_translate and

[gdal-dev] Progress and cancel of gdalwarp program

[Gane R]

Is that any way to get the progress of the gdalwarp and make a cancel
request of gdalwarp.

in gdal 1.10.1
In gdalwarp.cpp
 I see psWO->pfnProgress = GDALTermProgress;

This for only progress right ?

I want to have function called with the progress displayed and also check,
if cancel is requested.

[gdal-dev] Get EPSG code from WKT

[Gane R]

When I try to convert to different projection using the gdalwarp
*without *specifying
the* -s_srs option* it reprojects to a *different location*, for some
raster it projects to a correct location.

But when try to run gdalinfo and I see a lot of EPSG code, when I use the
last AUTHORITY EPSG code as -s_srs option the above mention problem is
solved.

Is it that I have use the last AUTHORITY EPSG code or any thing will help

[gdal-dev] Question on using SetFID

[Gane R]

Hi all,

I am creating a layer for geopackage, But I don't see the fid I set using
setFID here is my code flow.

Step1:
poLayer = OGRDataSource::CreateLayer();

Step2:
adding all the fields

Step3:
poFeature = OGRFeature::CreateFeature( poLayer->GetLayerDefn() );

then
Step 4:
poFeature->SetFID(100);
 setting to a layer using
 poLayer->CreateFeature( poFeature )

Step 5:

OGRFeature::DestroyFeature( poFeature );
then destroying the poFeature,
again creating the feature using Step 3:

Every thing is fine but the feature id is set to start from 1, but I was
expecting
as 100 for the code flow above,

did I miss some GDAL API call ?.

Thanks

Thanks for you timely response

I got it detected, what should be used for building GDAL with Windows,

For Windows I used an amagation version I wrote script to build as static
lib and ignored the default libs and got a static lib and build GDAL with
sqlite3. It worked, its that fine on windows.

[gdal-dev] Build gdal with sqlite3 support on linux

[Gane R]

I got a source of sqlite3 from amalgation. I compiled on linux to get a
static lib say libsqlite3.a

I want to build GDAL with sqlite3 support,

so I tried to use ./configure --with-sqlite3=path

the path has include folder and lib folder (as subfolder) containing the
libsqlite3.a

gdal failed to detect the sqlite3 in that specified location.

Is that I am doing correct. Can anyone point be the right direction, this
will be of great help.

Is that I have to build the sqlite3 separately and then build gdal, does
gdal have an sqlite internally like png (libpng)  if so how can it be used.

[gdal-dev] Building gdal with sqlite3 for windows

[Gane R]

Where do I get the sqlite3 with include header files, stub library
sqlite3_i.lib and dll.

Do I have to build it, If so I tried the following

I have a sql-amalgation version.
I tried to look the documentation on sqlite website for creating a
sqlite3.dll

using the following command
cl sqlite3.c -link -dll -out:sqlite3.dll

I got that, but sqlite3_i.lib was not there.

[gdal-dev] GeoPDF vs GeoSpatial PDF

[Gane R]

I have been browsing on the internet for finding the difference
between GeoPDF and Geospatial PDF. It seems that the terms geopdf and
geospatial are interchangeable used. Is the both geopdf and geospatial
are same, if so the PDF driver in gdal will handle  geopdf and
geospatial PDF.

Suggestions and references are appreciated.

It is weired, when I call CreateDataSource as I had discussed earlier, I
send a large filename with absoluted path to it. I causes a crash at when
called from java via jni


Is there any limitation in the name of the filename when passing to

Re: [gdal-dev] Writing Coded Domain Values from GDAL

[Gane R]

I just figured out the issue, I tried to see that the C.D.V are created on
the layer, but for XML with C.D.Vs the layer returned was NULL.
However it worked for XML without C.D.V values. Filegeodb API says that
call for geodatabase->createTable will ignore C.D.Vs

Thanks

[gdal-dev] Writing Coded Domain Values from GDAL

[Gane R]

I tried to read the coded domain values from GDAL, I used special sql
requests from GDAL as described in FileGeoDB driver. I got the values in
the XML format.

Is it possible to write coded domain values from GDAL using special sql
request.
I saw that it was possible from ESRI filegeodb API, can this be done from
GDAL itself.

How to convert Lat Long bounds to geotransform values for a particular zoom
in EPSG:4326


I can generated a raster with width, height and the geotransform values.

But for an Lat Long bounds at a particular zoom say highest 22, will the
xres and yres vary with location ?

Re: [gdal-dev] GeoPDF content inverted as GeoTIF

[Gane R]

Thanks for your timely response. Well the PDF was generated at the source
by different form such that I didn't face this problem, that new version of
the file worked for me.

[gdal-dev] GeoPDF content inverted as GeoTIF

[Gane R]

Here is link to GeoPDF which is inverted when converted to GeoTIFF


https://drive.google.com/file/d/0B4shTM1bPS5TNHBDVG45RzdWYjA/view?usp=sharing


Is it a problem in PDF or something with the PDF driver rotation.

[Gane R]

Q1. exportJson converts Geometry to Json, I am looking a function to
convert the json string to OGRPoint.

Please suggest your suggestions.

Q2. String returned by exportJson should be compulsorly freed using CPLFree

Hi all,

I tried to build *GDAL 2.0.1* with *filegeodb* support with *proj4* as
static lib on *Linux*. I am able to use the API to get the field data from
Filegeodb but I am *not able to get the geometry*.  I have configured as

./configure --with-fgdb=/fgdblib --with-static-proj4=/usr/local/

I am wondering what went wrong. But ogrinfo shows the values of the same
filegeodb file.

Thanks for your reply, I have a requirement that I should have two GDALs. I
have also an issue, I have build gdal 2.0.1 with proj4 as static, it does
not process the geometry inside from filegeodb. any thoughts will be
appreciated. I have the GDAL_DATA environ set, and pro4 share lib also
exist on the machine and ldconfig is also called to update the shared

[gdal-dev] Error building Gdal on Mac OS X with Filegeodb

[Gane R]

I was trying to build gdal-2.0.1 with Filegeodb (File Geodatabase API 1.4
version for Mac 64-bit (Gcc) for Mac running on intel OS X Yosemite 10.10.5

I get the error undefined symbols for architecture x86_64 at Filegeodb
modules. I think all the compiler and OS requirements are met.


I tried to build gdal-1.10 with Filegeodb on MAC it was not too successful.
I followed the step at
*https://gist.github.com/zhm/2005158 *
 I got error with @ECW@ and @LIB_XML@
gdal lib was not build.

Any suggestions will be appretiated.

[gdal-dev] PDF gets skewed and shifts in geo location raster GeoTIFF

[Gane R]

There are cases for handling 90 -90 rotation in pdfdataset.cpp
I am using poppler with pdfdataset.cpp as in Revision: 28978 of trunk

PDF gets skewed and shifts in geo location raster GeoTIFF, Is there any
issue in computing the geotransform ?

GeoTransform values are for an pdf at EPSG:4326

[gdal-dev] Increase width and change offset of the shape file rasterized

[Gane R]

Questions: 1. How can I change the width of the vector (shapefile) and
change the offset.

I see GDALdllImageLine calling - pfnPointFunc - calling gvBurnPoint

Questions: 2.  gdalrasterize generate transparent png of the raster

i know the png driver doesn't support create but create copy.

How about the buffer written to MEM driver and then to PNG driver. But I
want it to transparent and not black ?

Thanks for your previous replies.

[gdal-dev] Compute GeoTransform

[Gane R]

With Lat Long bound values how do create a geotransform for WGS84 GeoTIFF

I followed this link

https://trac.osgeo.org/gdal/wiki/FAQRaster#HowcanIcreateablankrasterbasedonavectorfilesextentsforusewithgdal_rasterizeGDAL1.8.0

or how do I use the -tr option for WGS84, GeoTIFF I want to have high
resolution image.

[gdal-dev] Creating a transparent GeoTIFF, writing shape data over it, reading GeoTIFF writing as PNG with transparency.

[Gane R]

1. Can I create a transparent GeoTIFF like PNG with alpha channel ?

2. Can I used gdal_rasterize to draw shape over the GeoTIFF with
tranparency

3. Can I read a part of the GeoTIFF using GDALRasterIO and write as PNG
with the same transparency preserved.

Say some kind of work flow with gdal command line tools will be of great
help.

[gdal-dev] gdalwarp skews and rotates PDF rasters, when converting to GeoTIFF, when PDF raster are in Landscape orientation or (True north facing botton or right or left)

[Gane R]

I am using gdal 1.10.1

I have a set PDFs, I am converting them to GeoTIFF.

I am using gdal with poppler for pdf  driver.

I have PDFs of places with orientation in Landscape, and north facing right
or left or bottom.

When I apply a gdalwarp for these PDFs I get unexpected rotation at GeoTIFF
output.

I read this link too

http://lists.osgeo.org/pipermail/gdal-dev/2014-June/039438.html


I need some guidance for this. Say some kind of work flow with gdal command
line tool will be of great help.

Thanking you,
Gdal gurus.
