I am completely new to GIS and I had hopefully a simple question regarding how to reduce the file size of my shapefile and associated database file. The files sizes are:
- Shapefile (.shp file format) is 50 mb
- Database (.dbf file format) is 50 mb
The attribute table information I have is:
- 12 fields
- length averaging 10-20 with precision averaging 0-1
- In total there is 417960 lines in the attribute table for each one of the 12 fields
With my data I also have a .prj file and .shx file. I have been trying to use QGIS 2.18.13 with GRASS 7.2.1 to convert the files into KML and also to change into NTD83 for use in IHS Accumap.
When I try to import the files into Google Earth the error message states there is over 2500 layers and even when viewing in restricted view it slows and crashes Google Earth. And IHS Accumap is very slow as well.
