Getting Data into ArcGIS Pro and Processing for Animation<\/strong><\/p><\/blockquote>\n

The data (historical population, by county, for your state) downloaded from the WWW must be processed in order to use it in ArcGIS Peo. There are two basic data processing tasks involved in this project. In Lab 3,<\/b> you used Excel<\/b> to clean up and combine your data into an Excel file.<\/p>\n

In Lab 5<\/b> you will import your\u00a0.xlsx<\/b>\u00a0file into ArcGIS Pro. <\/b>Additional processing is required to prepare the data for animation. For now, we are working with the total population data. In the past we have calculated percent population change (which is more interesting to map) but ArcGIS Pro is making this difficult to do with data intended for animation. I’ll update this lab when I figure out an easy way to generate the population change data.<\/p>\n

The Details<\/strong><\/p><\/blockquote>\n

The process below consists of getting a map of your state by counties, adjusting it’s map projection, then processing your total population data in ArcGIS Pro so that it can be animated. That data will be joined to the state map, and a few more adjustments made for animation.<\/p>\n

With the new ArcGIS Pro, this is a brand new lab with instructions that are bound to have some errors and typos. Let me know and I’ll fix them.<\/em><\/p>\n

    I’m using Wisconsin as an example. Substitute your state name.<\/em><\/p>\n

    Open ArcGIS Pro<\/strong> (shortcut on desktop)<\/p>\n

    Under <\/span>New ><\/strong>\u00a0<\/span>Blank Templates ><\/strong>\u00a0<\/span>Map<\/strong><\/p>\n

    Name<\/strong>: <\/span>Wisconsin<\/strong><\/p>\n

    Location<\/strong>: Documents\\ArcGIS\\Projects (yes, create a <\/span>new folder<\/strong> for this project)<\/span><\/p>\n

    Contents<\/strong>: change “Map” to Wisconsin<\/span><\/p>\n

    Right click on <\/span>Wisconsin ><\/strong>\u00a0<\/span>Add Data<\/strong><\/p>\n

    Navigate to:<\/strong> C: GIS Lab Data > ESRI > ESRIDATA_2000 > usa > counties.shp<\/span><\/p>\n

    Fun Facts: shape (.shp) files vs geodatabase (.gdb)<\/strong><\/em><\/p>\n

    \"\"<\/p>\n

    Click on Map<\/strong> tab<\/strong> at top (to right of Project)<\/p>\n

    Click on Select by Attributes<\/strong><\/p>\n

    In pop-up, next to Where<\/strong> select STATE_NAME<\/strong><\/p>\n

    is equal to
    \nselect <\/span>WISCONSIN<\/strong> > OK<\/span><\/p>\n

    We have selected WI out of the entire US!<\/em><\/p>\n

    Right click on <\/span>counties<\/strong> layer in <\/span>Contents<\/strong> (on left)<\/span><\/p>\n

    Selection<\/strong> > Make Layer from Selected Features<\/strong><\/p>\n

    Change name<\/strong> of new layer – “counties selection” – to Wisconsin Counties<\/strong><\/p>\n

    Right click on original “counties” layer in Contents > remove<\/strong><\/p>\n

    Also remove<\/strong> Topographic<\/p>\n

    In Map tab,<\/strong> click on small globe<\/strong> to upper right of Explore: full extent<\/strong><\/p>\n

    We are actually still using the counties.shp data, thus the extent is the entire US, but can’t see the rest. We need to\u00a0extract and save our state counties as a separate file.<\/em><\/p>\n
