Very slow to load Features from Shapefiles

A customer reported that it took a long time to load Shapefiles containing county property lines.

The U.S. county property line Shapefiles typically contain more than ten thousand polygons, along with a multitude of Attributes. As we mentioned in our 10/2/19 blog post, it will take time for the app to process a large job with a huge number of Features and Attributes. The app might also crash if a computation or file saving operation is disrupted for some reason.

Typically, you will want to just load the polygons that you need for a particular job, and not all of them. If you have a PC software program that will let you load the county property lines then let you export just the ones that you need, then please use it to prepare the corresponding Shapefiles for importing into the app.

Some of the iCMTGIS PRO customers use our PC-GIS X to accomplish this. PC-GIS X can import and export Shapefiles. So, the users would load the Shapefiles from the county then select the polygons they need to export to a new set of Shapefiles for importing into iCMTGIS PRO. After collecting GPS data, they would copy the .pmp file to their PC and open it in PC-GIS X. Then they will see the Feature data displayed along with the property lines . They will be able to make some changes, if they wish, then use the Plot Preview function to make a nice map for printing to a PDF file or a printer.

If you don’t need to refer to the property lines in the field, then you could simply load the county property polygons into PC-GIS X and combine them with the field data to complete the map.
