I have a question about joining data points (with a large amount of information) with shapefiles in ArcGIS Desktop:
- I have imported a CSV file into GIS. This CSV File is quite large: each row contains roughly 75 columns. As such, each row in the CSV file contains quite a bit of information. I was able to create an "Events" layer with the CSV document and display the information visually as a series of data points in GIS (each row of the CSV document has latitude and longitude coordinates to make this possible).
- It is my goal to spatially-join the data points with the polygon shapefile that that they fall inside of (please see the picture below). For a bit of reference the polygon is an island and the data point describes information regarding that island. Unfortunately GIS does not allow for this to happen because there is no OBJECT_ID attached to the data points. Additionally, exporting the data to create a new layer does not work because the amount of information is too large!
Any thoughts on how to overcome this issue?
I am quite new to GIS.
