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 🙂

Changing the symbols of an entire layer in ARCGIS

1 Feb

Hello!
As always, there are small things that make our life easier when we are working with Arcgis. But sometimes, they are so obvious and -small-, that we tend to forget how to do them :p

This time, a friend had a layer with many roads and he asked me how to do all of them thicker. To change them all at the same time you just go to:

Layer properties/Symbology/Symbol Tab (above the lines representing each of the roads in this case)
Left click/ Properties for all symbols

There you can change the properties of all your features at the same time 🙂

Happy modelling…
