DATAMAP v2.0 can do two jobs:
1) display datasets in the form of f(x,y)(for each (x,y) position
a specific property was measured) by five popular plots as a map.
2) Datasets in the form of f(x,y) contains [x,y,f(x,y)];
DATAMAP converts it to the 2D matrix WITHOUT or WITH applying
interpolation. Users can adjust the value of areas without data in
the matrix ( e.g., 0, NaN, Inf, etc.)
The following datasets can be displayed or converted by DATAMAP:

- Topography data
- Potential field data such as gravity, magnetic, etc.
- Cross-section data such as velocity profiles, geoelectric profiles

Version 1.0 (Fall 2019) DATAMAP v1.0 is written and tested in MATLAB R2013a.

Version 2.0 (Winter 2020) the following changes are applied:
1) In this version, the program is optimized, and it is faster
than the v1.1.
2) Also added the following options for handling big dataset
2-1) 'gridInterval' can upsample or downsample data
NOTICE: This version doesn't apply the anti-aliasing filter
in downsampling.
2-2) 'MaxSize' is a pre-defined maximum allowed matrix (map)
size. For the map, bigger than this value, the program
automatically finds the grid size that the map size become
smaller than MaxSize value (look at Inputs' help)
