[Gvsig_english] error when loading an asc grid into theview:known bug?

Thu Aug 7 22:07:15 CEST 2008

Hello, Christian. I think your raster is using a sophisticated color table:

    <Metadata>
      <MDI key="COLOR_TABLE_RULES_COUNT">10</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_0">0.000000e+00 1.400000e-02 255 255 255 249 244 193</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_1">1.400000e-02 2.800000e-02 249 244 193 255 255 0</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_2">2.800000e-02 4.200000e-02 255 255 0 234 90 0</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_3">4.200000e-02 5.600000e-02 234 90 0 255 0 0</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_4">5.600000e-02 7.000000e-02 255 0 0 159 0 2</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_5">7.000000e-02 8.400000e-02 159 0 2 148 0 132</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_6">8.400000e-02 9.800000e-02 148 0 132 106 19 133</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_7">9.800000e-02 1.120000e-01 106 19 133 0 166 235</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_8">1.120000e-01 1.260000e-01 0 166 235 46 28 134</MDI>
      <MDI key="COLOR_TABLE_RULE_RGB_9">1.260000e-01 1.400000e-01 46 28 134 20 0 67</MDI>
    </Metadata>

which probably means:

for values between 0 and 0.014 => color interpolation between 255, 255, 255 (white) and 249, 244, 193 (light yellow)
for values between 0.014 and 0.028 => color interpolation between 249, 244, 193 (light yellow) and 255, 255, 0 (pure yellow)
etc.

So maybe problem is that gvSIG is not using correctly this color table. I don't know if it is possible to change the layer properties in gvSIG to make that raster look good, or maybe with the raster pilot or with the Sextante extension. Sorry I cannot help you more myself.

Regards,
Juan Lucas

Dear list,

attached is the raster file which causes the problems.
Following the procedure described in your e-mail, no new log files were created, so I  just attached the  text file held in the ...user/gvsig folder.

Regards

Chris

>>> a strange error occurs after loading an .asc grid into the view (see attachement). Just a black frame appears with nodata values for the black frame (actually there are no nodata values) and inside there are no values.
