pytroll / areadef Goto Github PK

A small tool to graphically help the creation of area definitions in Pytroll. It's WIP and plenty of hardcoded stuff, it needs work before it can be used.

areadef's Issues

Two heights and no widths

When I use the installation at http://clemspace.ch/areadef/ to select an area near Crete with a resolution of 500 metre, I get:

crete:
  description: Crete and nearby islands
    proj: eqc
    ellps: WGS84
    units: m
  shape:
    height: 731
    height: 293
  area_extent:
    lower_left_xy: [2584716.7894244194, 3854960.1286649713]
    upper_right_xy: [2950317.3753619194, 4001444.5036649713]

Note that the shape has two heights and no width. The first one of those heights should be width.

Add more projection types

Add more projection types, in addition to stere and eqc.

Map display when projection is eqc

The map display when the projection type selected is eqc shall be improved, covering the whole world and not just Europe and Africa.

Make lat_0, lon_0 and lat_ts selectable.

When choosing the projection type stere, the parameters lat_0, lon_0 an lat_ts should be selectable, instead of fixed.

Script produces invalid YAML

Using the generator at http://clemspace.ch/areadef/ an example of YAML syntax I get is:

saotome:
  description: São Tomé and Ilhéu das Rolas
    proj: eqc
    ellps: WGS84
    units: m
  shape:
    height: 565
    height: 684
  area_extent:
    lower_left_xy: [705505.3673684598, -11606.849730014801]
    upper_right_xy: [761962.8868997098, 56752.52526998521]

Trying to read this using python -c 'import yaml, sys; print(yaml.safe_load(sys.stdin))' < areas.yaml results in a ScannerError:

yaml.scanner.ScannerError: mapping values are not allowed here

Comparing with satpy-builtin areas.yaml files, it appears there should be a line projection: immediately below the line starting with description:. If I add such a line, the YAML syntax appears correct (I can read it with pyresample.area_config.load_area).
