I have to create a fishnet (raster) with a certain extend. I have a .shp file which has the needed extend which i should use. But my collegue tells me that a cell size should be 2/3 degree (latitude) x 1/2 degree (longtitude). He gives me the example from:
But for me that makes not really sense, because i have the extend from my .shp?
Does someone know what my mistake it? I started now within ArcMap to create a fishnet for the .shp with the data:
Data Type: Shapefile Feature Class
Geometry Type: Polygon
Coordinates have Z values: No
Coordinates have measures: No
Projected Coordinate System: ETRS_1989_LAEA
Linear Unit: Meter
Geographic Coordinate System: GCS_ETRS_1989
Prime Meridian: Greenwich
Angular Unit: Degree
Like a spatial resolution for (deg lat x deg lon) 1/2 x 2/3 is needed but how can i combine this with the extention of my .shp?
Thank you so much in advance for your help!
