Georeferencing Vermont’s Historic Aerial Imagery in QGIS: How-to and Lessons Learned | by Cale Kochenour | Vermont Center for Geographic Information | Medium

Editor’s Preface: Obtaining, digitizing, georeferencing and publishing historical Vermont orthoimagery are some of the many things we at VCGI wish there were more time and resources to do. Fortunately, we’ve been lucky to have met Cale Kochenour, a Vermonter and current graduate student in GIS and remote sensing at Penn State. Cale has graciously volunteered not only to georeference some of the digitized old black and white VT orthoimagery we’ve collected over the years, but also document for others the process and lessons learned. Learn more about the imagery program here, and access imagery via the Vermont Open Geodata Portal here.

2020 Census Redistricting Data (P.L. 94-171) Shapefiles

Released in groups of states January 2021 through February 2021. Once complete, the 2020 Census Redistricting Data (P.L. 94-171) Shapefiles will be available for all 50 states, the District of Columbia, and the Commonwealth of Puerto Rico.

Why should you care if your not interested in the politicians and their self-serving redistricting efforts? Well, TIGER/Line data is very useful for making all kinds of maps where you need county and municipal lines, such as mapping cases of COVID-19 or any data you get from data.census.gov. Or even hiking or road maps when you want town lines on them.

The nice thing about the redistricting files is they are packaged up in nice big ol’ ZIP file for the whole state coverage, for easy downloading and use. Mid-redistricting cycle you will want to occasionally get the yearly updates to reflect changes in county, municipal and census tract lines, but those have to be individually downloaded. It’s better to download one big file, and have all the data you need at one shot.

putting it all together!

33 Map Elements to Include in Cartographic Design – GIS Geography

It’s time to create remarkable maps that make you an instant expert, attract positive feedback, and flood your portfolio with solid cartographic design output.

There’s no silver bullet for map design. It takes time and effort to create high-quality cartographic maps. Often, it entirely depends on user needs.

But there’s almost always reoccurring elements in map-making. That’s why we’ve put together this mapping checklist.
