[GRASS-user] Which colour palette is currently applied to a raster
Hi Users, How can I tell which colour palette set is currently applied to a raster in Grass 7.8.3? nothing is stated in metadata and checked in 'PERMANENT/colr' for colour palette 'name' but nothing. Many thanks, *Paul J. Shapley *MSc CGeog (GIS) FRGS ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Lost attribute connection - grass 7.6.1
Hi Users,
I often create vector data using 'r.to.vect' which vectorises with no
issues but If I then export it to PostGIS using 'v.out.postgis' the first
layer will export fully but consecutive layers fail with the following
error:-
GRASS_INFO_WARNING(4924,1): Table not found in
database using driver
GRASS_INFO_END(4924,1)
After which the table does not open again in grass. I've checked to ensure
both 'sqlite' and 'pg' connections are present. When I get the above error
I am connected to 'pg'
db.tables -p (shows me i'm connecetd to 'pg')
db.connect -p or -g
driver: pg
database: ##
schema: grass_gis
group: postgis_reader
(Tue Aug 06 15:56:34
db.connect -g
This is probably something obvious i'm missing!!
Thanks,
Paul Shapley

[GRASS-user] v.external
Hi Users, I've upgraded to Grass 7.6.0 (r 73958) and i've tried using 'v.external' to link to our Postgresql/PostGIS tables in the usual way but when I try to link no tables appear in the list. I've selected 'Database' 'ODBC' then entered PG:dbname=MyDatabase then I get the error:- *No Layers Selected. Operation Cancelled* If i enter 'db.tables -p' i can see all the tables and schemas listed and the 'VAR' file shows the connections so i think it is connecting OK. Thanks, *Paul J. Shapley* ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Image signature preview
Hi Users, I want to isolate a single signature created from an area polygon with i.class/g.gui.iclass. I can do this and preview the result i need but what I would like to do is create a full region map from the 'SIG' in order to display just the one category type of land (isolated in the training area and applied to the remaining map). How could I achieve this in Grass 7.4.1 Thanks, -- *Paul J. Shapley *MSc CGeog (GIS) FRGS ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] G_malloc errors in i.segment
Hi Marcus, Thanks again for your patience with this issue. It seems that whatever i set in the memory of 'i.segment' to it throws up the same 'G_malloc' error with the same 3 gb shortfall. I had another idea which is to make a smaller subset image (but if i do this) will the new subset of 'id' segments be applicable if applied to the entire image. For example if a value of '5134' represents 'peat' could i use 'r.mapcalc' to query the entire image for those values of '5134'. Supervised and Unsupervised Classification would not yield the differences in the landscape i'm looking for which 'i.segment' succeeds.

[GRASS-user] r.colors
Hi All, Just testing 7.0.2RC1 with some landsat 8 images. I've imported and changed the DN values to TOAR values but when i try to use a 'Histogram Stretch' using the 'grey' table the maps display no color (white display) whereas in version 6 it worked. Also i need to increase the 'contrast' when displaying the individual bands but dont know if there is a way to do this. I have tried opening the 'i.fusion.hpf' script but it seems to hang. Many Thanks, -- *Paul J. Shapley *MSc CGeog (GIS) FRGS ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Migrating to a different database engines in Grass 7.0.1RC2
Hello Grass Users, I would like to know why and where grass stores old database connection parameters set with 'db.connect' and 'db.login'. this is not in the 'VAR' file in the PERMANENT directory, I often switch between PostGIS and SQLite data but even if i add a new connection it seems to retrieve a three year old connection parameter and i dont want to keep having to create a new 'mapset' every time i change. Should i go back to 6.4 stable or is there another solution? Many thanks, -- *Paul J.

[GRASS-user] Projection errors
Hi Users, I'm having the problem of projecting a source map (landsat 8 image) into a target location (Ordnance Survey UK) in Grass 7. I have tried the r.pack/unpack method but i get the following error:- 'WARNING: Projection information does not match. Proceeding...' The resulting view shows both images but the landsat image is many kilometres to the north of where it should overlap. Have also made 'PROJ2'(see below) with the same n,s,e,w as 'PROJ1'(see below) but still the same result as above. As i understand it the underlying Landsat images are in the WGS84/lon-lat format. I'm wondering should i use m.proj to first convert the co-ordinates to OrdSurvey? I seem to recall just using 'r.proj' in the past with no problems at all but now i get error:- 'WARNING: pj_transform() failed: latitude or longitude exceeded limits' I'm a little confused as to which module to use to get around this problem. g.region -b north latitude: 89:59:47.524206N south latitude: 49:45:56.915978N west longitude: 18:03:37.69897W east longitude: 0:02:23.60354W center longitude: 9:03:00.651255W center latitude: 69:52:52.220092N 'PROJ1' - DEFAULT_WIND proj: 99 zone: 0 north: 5848507.5 south: 5605492.5 east: 540907.5 west: 300892.5 cols: 540915 rows: 5848815 e-w resol: 1 n-s resol: 1 top:1.000 bottom: 0.000 cols3: 1 rows3: 1 depths: 1 e-w resol3: 1 n-s resol3: 1 t-b resol: 1 'PROJ2' - DEFAULT_WIND proj: 99 zone: 0 north: 123 south: -123 east: 66 west: -66 cols: 108220 rows: 1169781 e-w resol: 5 n-s resol: 5 top:1.000 bottom: 0.000 cols3: 1 rows3: 1 depths: 1 e-w resol3: 5 n-s resol3: 5 t-b resol: 1 Thanks, -- *Paul J.

Hi Users, Having some problems moving some landsat 8 composite images into a different location/mapset with the same projection. Have tried r.proj (this produces the 'ERROR: Input raster map is outside current region') and v.in.region method (this produces a 'blank' map).

[GRASS-user] Landsat 8 Workflow for Grass 7.0.0RC2
Hi Grass Users, I want to use the following Landsat 8 workflow to obtain some pansharpened images but have a problem when i convert the DN values to 8bit for pansharpening. Here is my preferred workflow in Grass 7.0.0RC2. · r.in.gdal (success) · i.landsat.toar (success) · r.rescale bands 432 8 (convert reflectance 'DN' values to 0-255, 8bit) · i.pansharpen bands 432 with 8 · r.rescale (convert 0-255 values back to reflectance 'DN) · i.colors.enhance (pansharp bands) · d.rgb My question...is this a valid workflow? because i'm getting the same two errors below and the images when displayed look solid grey when viewed with d.rgb:- *displaying the pansharpened images error log:-* (Tue Feb 17 14:57:26 2015) g.list rast LC82040242014206LGN00_B1 LC82040242014206LGN00_B10 LC82040242014206LGN00_B11 LC82040242014206LGN00_B2 LC82040242014206LGN00_B3 LC82040242014206LGN00_B4 LC82040242014206LGN00_B5 LC82040242014206LGN00_B6 LC82040242014206LGN00_B7 LC82040242014206LGN00_B8 LC82040242014206LGN00_B9 LC82040242014206LGN00_BQA LC82040242014206LGN00_refl1 LC82040242014206LGN00_refl10 LC82040242014206LGN00_refl11 LC82040242014206LGN00_refl2 LC82040242014206LGN00_refl3 LC82040242014206LGN00_refl4 LC82040242014206LGN00_refl5 LC82040242014206LGN00_refl6 LC82040242014206LGN00_refl7 LC82040242014206LGN00_refl8 LC82040242014206LGN00_refl9 LC82040242014318LGN00_B1 LC82040242014318LGN00_B10 LC82040242014318LGN00_B11 LC82040242014318LGN00_B2 LC82040242014318LGN00_B3 LC82040242014318LGN00_B4 LC82040242014318LGN00_B5 LC82040242014318LGN00_B6 LC82040242014318LGN00_B7 LC82040242014318LGN00_B8 LC82040242014318LGN00_B9 LC82040242014318LGN00_BQA LC82040242014318LGN00_refl1 LC82040242014318LGN00_refl10 LC82040242014318LGN00_refl11 LC82040242014318LGN00_refl2 LC82040242014318LGN00_refl2_rescale LC82040242014318LGN00_refl3 LC82040242014318LGN00_refl3_rescale LC82040242014318LGN00_refl4 LC82040242014318LGN00_refl4_rescale LC82040242014318LGN00_refl5 LC82040242014318LGN00_refl6 LC82040242014318LGN00_refl7 LC82040242014318LGN00_refl8 LC82040242014318LGN00_refl8_rescale LC82040242014318LGN00_refl9 (Tue Feb 17 14:57:27 2015) Command finished (0 sec) Command 'd.rast map=LC82040242014318LGN00_pansharp@PERMANENT' failed Details: Raster map LC82040242014318LGN00_pansharp@PERMANENT not found *i.colors.enhance error log:-* (Tue Feb 17 13:06:40 2015) i.colors.enhance red=LC82040242014318LGN00_B4@PERMANENT green=LC82040242014318LGN00_B3@PERMANENT blue=LC82040242014318LGN00_refl2@PERMANENT strength=96 Processing...

Hi, This flood module is working in the latest stable release, however there is an issue in that it does not produce the flood 'test1' map only 'test2' (the MTI map). Running the module seems to generate three maps 'r.clump', 'r.flood' and 'test2'. Just need confirmation that this is how it is meant to be and is the error below normal or does the module require fine tuning. Also is there any detailed information on this module?

Also when the layer is open applying a simple query in the attribute table manager fails to get any results it just appears to freeze (not responding). It is does not zoom to attribute like other layers but zooms out to map extent instead. I have checked topology with v.build and it seems all okay.
