This is an old revision of this page, as edited by Yug (talk | contribs) at 19:59, 13 June 2011 (→Topography/Bathymetry). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This QGis mapcolor files page already has some palettes you can use. Simply copy-paste the code into a text document, then save as PALETTENAME.qml. Then, in QGis and while working on a layer : 

QGis > LAYER > Properties > Load a style > [browse, select the .qml file, load] > Apply

 —Moreover : 1. since the Graphic labs developed a set of Map Conventions with encouraged colors, this QGis mapcolor files page will soon be expanded accordingly. 2. if suitable GIS files are available online, a description and link toward this GIS file will be provided.

Topography/Bathymetry

Scope: positive (topography), neutral (coastlines), and negative (bathymetry) altitudes. Exclude: Mars, Moon, and water bodies (rivers, lakes), for this, see specific sections.

CGIAR-CSI: SRTM3 v4 (2008?, Non commercial). Specifics: topography layer(s), 1px= 90m (3"arch), 60⁰N-56⁰S (landmass only), projection ?, datum WSG 84. Files: compressed file ~6Mo, uncompressed file ~25Mo, 5⁰x5⁰arch, ~1,000 tiles. —♣ Comment(s): Non commercial license not compatible with Wikipedia. Perfect for small areas all around the world. Complex to manage (many tiles). nb: CGIAR-CSI = Consultative Group on International Agricultural Research, Consortium for Spatial Information.
  • NASA: SRTM1 v.2.1 (2000, Public Domain). Specifics: topography layer(s), 1px= 31m (1"arch), USA and dependencies (landmass only), projection ?, datum WGS 84. Files: compressed file ~4Mo, uncompressed file ~30Mo, 1⁰ x 1⁰arch,. —♣ Comment(s): for mapmaking of the USA. File name from the lower-left corner's coordinates (ex: N48E001.hgt.zip)
  • NASA: SRTM30 (2000, Public Domain). Specifics: topography layer(s), 1px= 930m (30"arch), 60⁰N-56⁰S (landmass only), datum WGS 84.

File namimg from the top-left corner's coordinates. 12 files in the online folder, 10 are useful (to exclude: *.jpg.zip et *.gif.zip, which are previews). In 3DEM, après avoir décompressé ces 10 fichiers, sélectionner l'option GTOPO30 Tile puis dans la nouvelle fenêtre représentant la carte du monde, centrer le cadre sur la région d'intérêt et spécifier comme projection Lat/Lon. Naviguer dans l'arborescence et sélectionner le fichier .DEM.
  • NASA: SRTM Water Body Data (SWBD) (2000, Public Domain). Specifics: water bodies (major rivers, lakes, coastlines) layer(s), 1px= 31m (1"arch), 60⁰N-56⁰S (landmass only), datum WGS 84.

  • other local GIS resources

Borders (lines)

Scope:

  • Admin level 0 : Countries polygons
  • Admin level 1 : State/Provinces polygons
  • other local GIS resources

Others cultural

Scope: parks, urban areas, roads (OSM), buildings, towns, etc.
