topic Ratio Land/Sea within a buffer in ArcGIS Spatial Analyst Questions https://community.esri.com/t5/arcgis-spatial-analyst-questions/ratio-land-sea-within-a-buffer/m-p/596299#M8675 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><SPAN>i can't solve this problem. I am explaining analytically:</SPAN><BR /><SPAN>i have a DEM with elevations from my country, a shapefile with points of meteorological stations and coastline of my country. I create buffer around the points i.e. with radius of 5 Km. I want to calculate the ratio between sea and land within this buffer zone of 5 Km radius. For example, i want the final result to show that inside the circle of 5 Km the ration (land/sea) is 0.8.</SPAN><BR /><SPAN>Is there any solution for this?</SPAN><BR /><BR /><SPAN>Thanx a lot on account</SPAN></BODY></HTML> Tue, 30 Aug 2011 06:46:37 GMT StavrosKeppas 2011-08-30T06:46:37Z Ratio Land/Sea within a buffer https://community.esri.com/t5/arcgis-spatial-analyst-questions/ratio-land-sea-within-a-buffer/m-p/596299#M8675 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><SPAN>i can't solve this problem.
