Creating shapefile from lat/long values using ArcPy?

Creating shapefile from lat/long values using ArcPy?

How can I create a shapefile using Python in ArcGIS 10?

I have lat & long.

From this I need Python code which will create a shapefile in ArcGIS Desktop 10.

For creating points:

ptList =[[20.000,43.000],[25.500, 45.085],[26.574, 46.025], [28.131, 48.124]] pt = arcpy.Point() ptGeoms = [] for p in ptList: pt.X = p[0] pt.Y = p[1] ptGeoms.append(arcpy.PointGeometry(pt)) arcpy.CopyFeatures_management(ptGeoms, r"C:Temp	est.shp")

It will return a message like this:

Another option would be to just use the existing arcpy geoprocessing tools, see code below.

# Import arcpy module import arcpy # Local variables: table_dbf = "C:	emp	able.dbf" table_Layer2 = "table_Layer2" point3_shp = "C:	emppoint3.shp" # Process: Make XY Event Layer arcpy.MakeXYEventLayer_management(table_dbf, "x_coord", "y_coord", table_Layer2, "", "") # Process: Copy Features arcpy.CopyFeatures_management(table_Layer2, point3_shp, "", "0", "0", "0") mxd = arcpy.mapping.MapDocument(r"C:	empUntitled.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] addLayer = arcpy.mapping.Layer(point3_shp) arcpy.mapping.AddLayer(df, addLayer, "BOTTOM") mxd.saveACopy(r"C:	empUntitled1.mxd")

You can create a shapefile in Python using the Create Feature Class tool. There is an example at the bottom of the page.

To populate the shapefile with your lat & long data, you can use an Insert Cursor.

Perhaps you can load your lat & long data as a list into Python, then iterate through the array populating the rows of your new shapefile with the insert cursor.

A python list of coordinates can be constructed like this:

latLonList = [[40.000,-75.000],[39.998,-75.432],[39.981,-75.343]]

Then to iterate through coordinates in the list (and print them, for example), do this:

for coord in latLonList: print "lat: " + str(coord[0]) print "lon: " + str(coord[1])
