GIS and Google Earth

24 Feb

Hello again guys!

Today somebody asked me about getting GIS data into google earth.

This software has the great advantage that you can see loads of different data that you don’t necessary have in your regular GIS, such as pictures of a site that is of your interest uploaded by the community , tracks, wikiinfo and so on. So there are good reasons for you to want your gis regular data displayed here. The problem that my friend had was that when he “imported” his data into google he realized that it was a little bit “off” place.

Ok. This is basically due because the coordinate system he used was the one he had originally set for his data. KML only supports WGS84, so in order for you to display your data correctly you need to “reproject” your data to to WGS84. In arcgis (as in other software) this is really easy.

Happy modelling 🙂

How to batch merge multiple shapefiles

11 Feb

Hey guys, in one of my last posts I shared a very useful tool to split a shp into several by attribute.  I found another great script by Gerry Gabrisch but this time to merge multiple shapefiles. There are several ways to do this and if you are not that familiar establishing the arguments or parameters in a Phyton script you will probably prefer this other utility.

Tlaloc bless the internet! 😀

Have a great weekend!

Converting a single shapefile into several (Split by attribute)

8 Feb

Hello again!

Just a quick note to tell you that today I found a very useful tool set to split a layer or shapefile in many shapefiles based in an attribute from the table.

This is a very quick way to separate a layer of roads, counties and so on. It was created by the USGS and have also another 3 additional tools.

I hope is as useful for you as it was for me 🙂
