I´m beginer user of MOHID GIS and i have some problems to make my grid. Data items are:
- \".Xyz\" , with structure:
<begin_xyz>
397308.57 6444322.4 0.1
397802.2 6443689.7 0.1
.
.
767239.32 6825202.6 100
776371.7 6854927.4 100
<end_xyz>
-\".xy\". with structure:
<beginpolygon>
28799.095 6122068.4 0
34388.511 6126820.2 0
40978.432 6129302.4 0
.
.
159431.4 6135870.4 0
28799.095 6122068.4 0
<endpolygon>
- \".grd\", created in MOHID GIS
Obs.: All points of bathymetry are positive
First probleman is: the data items of \".xyz\" have some points out of the points to correct bathymetry and \".xy\" some points out of the polygon,
how can i take off then?
SEcond, After imported thats data itens, i used the tool´´ Create Digital Terrain'' , that created data item \".dat\". The problem is that: why when i visualize this archive, all points of grid are with
value -99? Like this:
.
.
4900.000
5000.000
<EndYY>
<BeginGridData2D>
-999.0000
-999.0000
.
.
-999.0000
-999.0000
<EndGridData2D>
I hope answers, please
Thanks so much
Lilian
