| | 9 | == Proposal == |
| | 10 | |
| | 11 | === Basic NC location with PERMANENT mapset === |
| | 12 | |
| | 13 | This is practically the gisdemo location with some updates. |
| | 14 | |
| | 15 | * loc_ncspm_baseline |
| | 16 | * PERMANENT |
| | 17 | * raster: |
| | 18 | * elevation |
| | 19 | * elevation_shade |
| | 20 | * landuse |
| | 21 | * basins |
| | 22 | * orthophoto(?) |
| | 23 | * soils? |
| | 24 | * lakes? |
| | 25 | * geology? |
| | 26 | * vector: |
| | 27 | * boundary_region |
| | 28 | * boundary_state |
| | 29 | * census |
| | 30 | * streams |
| | 31 | * streets |
| | 32 | * railroads |
| | 33 | * schools |
| | 34 | * hospitals |
| | 35 | * firestations |
| | 36 | * points_of_interest |
| | 37 | * historical sites |
| | 38 | * geonames |
| | 39 | * geology |
| | 40 | * sqlite |
| | 41 | * mymapset1 |
| | 42 | |
| | 43 | === Specialized mapsets === |
| | 44 | |
| | 45 | That can be inserted into baseline location - each will need to be distributed with a barebone location/PERMANENT so that it is readable by GRASS without the baseline data set. |
| | 46 | |
| | 47 | Providing just mapsets did not work, it was very confusing for users. But perhaps the only problem was that that "GRASS welcome screen" cannot unpack (unzip, untar) a mapset and copy it into an existing mapset. |
| | 48 | |
| | 49 | * mapset_ncspm_dem |
| | 50 | * mapset_ncspm_landsat |
| | 51 | * mapset_ncspm_networks |
| | 52 | * mapset_ncspm_orthoimg |
| | 53 | |
| | 54 | === Basic world location === |
| | 55 | |
| | 56 | * loc_world_ll_baseline |
| | 57 | * PERMANENT |
| | 58 | |
| | 59 | * specialized mapsets |
| | 60 | * mapset_ll_climate |
| | 61 | * mapset_ll_landcover |
| | 62 | |
| | 63 | == Notes after HVA discussion with Hamish == |
| | 64 | |
| | 65 | * barebone dataset for OSGeo Live which will include a script to generate the derived data needed for tutorials (?) |
| | 66 | * metadata |
| | 67 | * maps (layers) |
| | 68 | * exclude layers which can be generated |
| | 69 | * secref elevation? + orthophoto |
| | 70 | * add NC WMS service to GUI |
| | 71 | * soils, geology, lakes just vector |
| | 72 | * elevation, landuse, orthophoto |
| | 73 | * fields - parcel plots - with anonymized names - for secref - planimetry |
| | 74 | * SPOT image |
| | 75 | * elevation and precipitation points into baseline |
| | 76 | * add zipcodes |
| | 77 | * powerlines (extended) |
| | 78 | * separate layers for state and counties boundaries |
| | 79 | * natural earth for latlon dataset |
| | 80 | |
| | 81 | |
| | 82 | == Comments == |
| | 83 | |
| | 84 | The data sets can be distributed separately or we can have packages with several mapsets or all mapsets, depending on the size. |
| | 85 | I found that packaging and distributing mapsets without location is not practical, so I ended up distributing the specialized mapsets with nc_spm_baseline or world_baseline - is this OK?. |
| | 86 | We also need to figure out how to include the original metadata that come with the original data - link to the source in history file may be enough. |
| | 87 | |
| | 88 | The baseline location+mapset should be simple with easy to understand names of map layers, |
| | 89 | my only issue is the loc_ncspm_baseline name as I am not able to come up with |
| | 90 | a simple name that would say that this is a location with North Carolina data in state plane meters coordinate system - maybe loc_ncarolina would be better, assuming that state plane in meters is the official coordinate system for NC? But I also keep ncspf for feet and ncutm. |
| | 91 | |
| | 92 | == Notes about data sources == |
| | 93 | |
| | 94 | There is a lot of data, main challenge now is to select a consistent, meaningful, but not too large data set. |
| | 95 | Many data sets are regularly updated and new ones are posted but tutorials and man pages require stable data to work |
| | 96 | the history file should include link to the original data source with a note that an updated version of the data map be available from there |
| | 97 | |
| | 98 | Significant natural heritage areas and natural heritage element occurrences posted on NC one map. |
| | 99 | |
| | 100 | |
| | 101 | == TODO == |
| | 102 | |
| | 103 | ''List of actionable items.'' |
| | 104 | |
| | 105 | * replace historical markers with historical places (done?) |
