[gdal-dev] Improvements in GDAL Grid 2.01 vs 1.11.2 report

Hi, I have been using Gdal_Grid to interpolate LiDAR files. I use the NN algorithm. I order to reduce any border effect, I have been stitching all of my files together creating one big file. This created problems. The first being the GDAL_Grid had a 16mb buffer and needed to recalculate th

Re: [gdal-dev] generate raster "GeoTIFF" for given lat long bounds at particular zoom using GDAL

Hi, If you want a standard x and y, you will need to reproject using a projected coordinate systems like (WGS84/UTM Zone 18). Then, you will get a square pixel resolution that is in meters. If you use WGS84 Long-Lat, grids or pixels are almost square at the equator but become more and more

[gdal-dev] Empty .prj file with gdal_contour

Hi, On windows_64, a) When I launch a .bat file with gdal_contour from a dos prompt (from C:\GDAL1p5GBBuffer\bin or from C:\OSGeo4W64\bin ), I get an *empty* .prj file. b) When I launch the same .bat file with gdal_contour from the OSGeo4W64 Shell, I get a *proper* .prj file. Why??? My Wi

[gdal-dev] Null data and CRS. gdal_warp overkill???

Hi, I am creating a Windows .bat files with a Python script to make DEMs with LiDAR points. The idea is simple. 1) read input txt file to get the cloud geometries 2)gdal_grid with nodata value marker set to -32768 3)gdal_warp with -dstnodata to set the value marker (of grid created in step
