‎XYZ Points file

New page

== Overview ==
XYZ points are use do define discrete geo-referenced information. This information is stored associating X and Y coordinates to an attribute. Examples of applications of these items are: bathymetric or topographic surveys, water quality analysis results, etc.

== XYZ Points file ==
XYZ Points items are stored in an ASCII text file. The default extension for XYZ Points files in [[MohidGIS]] is '''*.xyz'''. This file is organized in [[blocks]], each containing the coordinates for a certain attribute. One block is defined by the following keywords: '''<begin_xyz>''' and '''<end_xyz>'''. Note that these keywords are case sensitive. One file can contain an infinite number of blocks. Inside each block there at least 3 columns. The left column represents the XX coordinates of the polygon vertices and the right one to the YY coordinates of the polygon vertices. The third column contains the attribute value. A fourth column can be optionally included and it is handled as a character string which can also be used as a legend for each point.

== Example ==
=== Three columns ===

<begin_xyz>
-9.138328 38.737320 292.
<end_xyz>

=== Four columns ===

<begin_xyz>
-9.138328 38.737320 292. MARETEC - IST (Lisbon)
<end_xyz>
