-----------------------------------
> Add an ESRI ASCII Grid reader and writer
> ----------------------------------------
>
> Key: SIS-540
> URL: https://issues.apache.org/jira/browse/SIS-540
> Project: Spatial Information Systems
> Issue Type: New Feature
> Components: Storage
> Affects Versions: 1.1
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Major
> Fix For: 1.2
>
>
> Add a reader and writer for ESRI ASCII Grid format. This is a very simple
> format easy to implement, and used commonly enough for being worth to be
> supported. See the [Wikipedia page|https://en.wikipedia.org/wiki/Esri_grid]
> for a format description.
> The reader/writer to implement in SIS are ports from the Geotk
> {{AsciiGridReader}} and {{AsciiGridWriter}} classes. Compared to the ESRI
> ASCII Grid format, the SIS implementation will have the following extensions.
> The 2 first extensions in this list exist also in GDAL:
> * Coordinate reference system specified by auxiliary {{*.prj}} file. If the
> format is WKT 1, the GDAL variant is used (that variant differs from the OGC
> 01-009 standard in their interpretation of units of measurement).
> * {{DX}} and {{DY}} parameters in the header are used instead of {{CELLSIZE}}
> if the pixels are non-square.
> * Lines in the header starting with {{'#'}} are ignored as comment lines.
