Calculating Geometry in ArcGIS Pro

A prior video from @DEEGSNCCU discusses how to calculate new columns from existing columns. However, what if we want to calculate the area, centroids (X and Y) or perimeter of our features? The Calculate Geometry utility is able to do this using projection information to calculate area in different units such as square miles, acres or square feet. More robust calculations allow you to calculating the minimum X, minimum Y, number of parts and even the number of holes (for polygons).

These videos have been created in support of teaching and research in the field of GIS (Geographic Information Systems) for the Department of Environmental, Earth and Geospatial Sciences at North Carolina Central University (NCCU). Established in 1910, NCCU is located in Durham, North Carolina, and serves about 8,500 students. The mission of our department is to promote intellectual, professional, and personal excellence through the highest quality instruction, research, and service in the environmental, earth and geospatial sciences. Its vision is to be recognized as a regional, statewide, and national resource for students and society as well as professionals who work in the many fields that are encompassed by the environmental, earth, and geospatial sciences. Students in our programs currently focus their studies in the fields of seismology, natural hazards, GIS (Geographic Information Systems) and Remote Sensing applications, environmental health & impacts and remediation technology among others. Our courses are designed to provide students with the analytical and methodological skills necessary to understand or derive explanations for individual occurrences, for recurring processes, and for invariable as well as statistical regularities in the earth’s lithosphere, hydrosphere, atmosphere, and biosphere. The department prides itself in former students who fostered these skills and have gone onto successful careers in the field at places such as the North Carolina Department of Transportation, City of Durham, Environmental Protection Agency, Lowe’s Corporation, Environmental Protection Agency, National Forest Service, Army Corps of Engineers, real estate firms and private contractors or students who have gone onto Ph.D. programs at places such as North Carolina State University, North Carolina A&T State University and the University of North Carolina, Greensboro.

Being self taught, this video showed me quickly how to add SF, Acres, Hectares to my attribute table (pick DOUBLE, and 2 decimal places). Thank you!

What's the difference between Sq Ft and Shape_Area? I noticed the whole numbers matched on your example, but the decimals differed.

What program did you use to share your screen like this?

Hi, is there a script to get basic information such as line length and start and end coordinates of a line segment by simply double clicking on the line?

I’m adding field and acres and it rounds it up to while numbers… how can I get it to give me unrounded in tenths of an acre? I seen where I add decimal places but it doesn’t change the numbers and I’m doing something wrong I guess. Thanks

Hi, maybe you can help me.
I have a layer with multiple polygons of different shapes and sizes and I need to make calculations using the length of the southest edge. Any idea how can I generate this type of data?
Thank you
