What can you do with NumPy in ArcGIS?
Numerical Python (NumPy) is a fundamental package for scientific computing in Python, including support for a powerful N-dimensional array object. NumPy allows you to perform complex mathematical operations and has been part of the ArcGIS software installation since 9.2. For more information, see the NumPy website.
Can a NumPy array be converted to a table?
To convert NumPy arrays to tables and feature classes, the arrays must be structured arrays. Structured arrays include fields (or structs) that are used to map the data to field in ArcGIS table and feature classes. For more information on structured arrays, see Structured arrays.
Can a raster be converted to a NumPy array?
You may want to convert an ArcGIS raster to a NumPy array to do the following: Implement one of the many existing Python functions that can be applied to a NumPy array (for example, run filters on the data, perform multidimensional analysis, or use optimization routines).
Can a feature class be converted to NumPy?
Converts a feature class to NumPy structured array. NumPy is a fundamental package for scientific computing in Python, including support for a powerful N-dimensional array object. For more information, see Working with NumPy in ArcGIS.
How to return true to masked array in NumPy?
Returns True if any of the elements of a evaluate to True. Count the non-masked elements of the array along the given axis. Count the number of masked elements along the given axis. Return the mask of a masked array, or nomask. Return the mask of a masked array, or full boolean array of False. Return the data of a masked array as an ndarray.
How to find unmasked data in a masked array?
Find contiguous unmasked data in a masked array along the given axis. Find the indices of the first and last unmasked values along an axis. Returns a list of slices corresponding to the masked clumps of a 1-D array.
