Mapping Mars with ArcGIS Pro

I only discovered relatively recently that the Desktop suite is not limited to mapping Earth. Hidden amongst the thousands of coordinate systems available, you can find those for mapping planets within the Solar System.

Just for kicks, I downloaded all the geological data from Mars to have a look in ArcGIS Pro and see how it would fare in the hybrid 2D/3D interface.

You can try this out for yourselves by downloading the data from the USGS here. The datasets are conveniently provided in a file geodatabase and the layers come with some standard symbology in MXDs, so it’s an easy feat to import into ArcGIS Pro.

Rinse and Repeat! Working with Modelbuilder Iterators

 

Modelbuilder is often an afterthought to most GIS analysts, however, it can be a powerful tool when it comes to building and replicating complex workflows, as well as automating those boring, tedious tasks.

Iterators are unique to models, and allow you to loop through a process on unique values, tables, layers in your map document, or even workspaces.

Let’s have a look at iterators, and how you can use them.

Five New Tools You’ll Meet in 10.1

Here are some of my favourite new tools and improvements that have come with the 10.1 release. These should make your mapping and workflows just that much more enjoyable.

1. Searching for a projection

With ArcMap shipping with over 4000 projections, it is easy to feel a bit overwhelmed, especially if you are a new user. Although you have always been able to save the frequently used projections to your favourites, you can now input keywords and find exactly what you are looking for. If you have no idea what you are looking for, you can even let ArcGIS use your current extent to suggest the best projection.

2.Enable Editor Tracking

Trying to figure out who moved that feature without telling you? Now with Editor Tracking enabled on your feature class, any new features or modifications will be logged with the username and time/date of creation or modification. This works with SDE databases as well. This is going to make your metadata housekeeping a lot easier. Note: This will not tell you if a feature has been deleted – best to use versioned geodatabases for that.
