I'm a software developer, focused on GIS. PostGIS and GDAL committer. I'd love to add 'where' to people's lives.

comment Fill holes with an area bigger of a specific value in a raster coverage
Thanks. Looks like GRASS is going to be the solution.

comment Why can't I perform any operation over a 700MB MIF file containing 5 multipolygons? It takes forever
Yep, that's what I'm trying to do. Seems to work modifying some PostgreSQL configuration parameters. I'll answer the question to show them. Thanks!

Yes, I think something went wrong because the table looks small. But ok. Please see update. And thanks for your response!

Ok, sorry for my stupid comment. And thanks!

comment ogrinfo returns a negative coordinate for extent of mif data file
Thanks! Just a question: how did you get that red polygon? I guess you used the TOWGS84 parameters and the extent coordinates.

comment GeoDjango: read geometry column in geography field
I got write access to the table, and created the geography field. Anyway, that solution worked too. Many thanks!

comment Hot could I generate a CRS field inside the GeoJSON object created by Leaflet layer.toGeoJSON?
Thanks! You're right. For any reason, I was thinking about epsg:3857 as a not projected CRS, what obviously isn't. Those coords are 4326, of course. Silly me!

comment min function not found compiling osrm
It makes sense. I finally used a Mac OS X machine with a 64bits kernel, and it worked. So, you're probably right.

comment min function not found compiling osrm
I finally compiled OSRM in a Mac OS X machine. So, I didn't continue with this way. But I think DennisL found the problem. It makes sense.

Oh, thanks for that. Much better title now.

comment Doubts about how pgRouting topology is built and how flexible it is
Yes, probably. But I think I have a better idea now, after reading the documentation and make a few tests. It seems that there's no automatic way of doing this. It's a question about how you define your data.

comment Is there an open source directions webclient for pgRouting like the directions API from Google?
Happy to hear that. I hope you can use it.

About the different level intersections, I think it's explained here: goo.gl/ojGmuH

comment Doubts about how pgRouting topology is built and how flexible it is
Ok, many thanks. I just have one doubt, about the different level intersection: You say "you'll have to make sure that there are no nodes within the specified tolerance". But the point is I start with just a few lines, and I want pgr_createTopology that do the job, and create the necessary vertices to connect my network. I don't know anything about nodes. I just want to specify in some way: "Ey, do you see that point where those 2 lines cross? That's not an intersection. They're at different height. Please, don't create a node there". But I think the response is here goo.gl/ojGmuH

comment Doubts about how pgRouting topology is built and how flexible it is
Thanks for your responses. I just keep a doubt. About 1 and 2, my point is that I just start with a bunch of lines in my table. One per row. I guess pgr_createTopology works creating a node per each intersection between lines. So, it decides where the nodes are. And if I want to represent that two lines intersect at a different level, it shouldn't create a node at that point, because there's no real intersection (example: a bridge over a motorway). I don't think it can do it.

You're right. I've already changed, keeping the original questions at the end.

comment min function not found compiling osrm
I've installed boost 1.49 and later boost 1.55, but looks that boost 1.49 is first detected. And I didn't pass any argument to CMake

comment min function not found compiling osrm
That change caused a lot of "undefined reference to boost..." errors. I guess boost is not properly found (strange, because I ran a simple C++ code to show boost version and worked). Anyway, changing the sources in order to compile sounds odd for me. Thanks anyway.

comment How to export raster from PostGIS enabled DB as GTiff with gdal_translate
Ok. So, you stick with ogr2ogr. If you installed GDAL properly (and looks that you did, because PostGIS found it), ogr2ogr is installed. Probably at /usr/local/bin. Check if that path is added to your system's path. And ensure where ogr2ogr is with: sudo find / -name ogr2ogr

comment How to export raster from PostGIS enabled DB as GTiff with gdal_translate
You don't need FWTools to use ogr2ogr if you compiled GDAL. It's included. You may need to add the path where the new GDAL installed the binaries (gdalinfo, gdal_translate, ogr2ogr...) to system path, if your problem is those commands are not found. About pgsql2shp, is not related with GDAL, and as long as I know, it's not packed with FWTools. It's a PostGIS tool. Which version of PostGIS are you using?
