[wiki:Haiti] == Haiti GIS == bitner, gavin_t, flavour & tcarobruce coordinating in #sahana-gis dokotreas joined the team === Map-based Lat/Lon Data entry === * Provide a function to allow selecting a location on a map to populate * Points: Lat/Lon fields * Polygons: WKT === Fix the map-based gis_location.represent === Currently this is commented out in {{{models/03_gis.py}}} Want to separate out HTML representation .represent's from Export ones (i.e. all the rest). * Plan for this in-progress === MGRS === * Add MGRS Coordinate Display to Map * Chris Schmidt made MGRS / Lat Lon mouse position control using Jim Klassens USNG Lib * map.addControl(new OpenLayers.Control.MGRSMousePosition()); * Example Code http://hypercube.telascience.org/haiti/js/haiti.js * Using http://hypercube.telascience.org/haiti/js/usng2.js * And http://hypercube.telascience.org/haiti/js/MP.js * Add Clickable Index (KML,GeoRSS, or Queryable WMS) to get to MGRS Map Sheets begin Produced by Talbot Brooks === Bugs === * #87 * #91 * #109 === Admin UI === * Provide admin UI for feature_to_feature_group, feature_class_to_feature_group, etc * {{{controllers/gis.py}}} & {{{views/gis/...}}} * Features are stored in the table gis_location * Feature Classes are types of Feature & determine their Marker (Icon): gis_feature_class * Feature Groups are collections of Features & Feature Groups & determine whether they appear as a separate layer on the Map to be enabled/disabled: gis_feature_group * There are Many-to-Many tables linking these together (defined in {{{models/03_gis.py}}}) * There are basic Controller functions for editing these resources, however they aren't fully-exposed to users (need to type URL manually) * We want nice User interface for these & menus (menus for GIS need some wider cleanup work anyway) * Allow to reorder layers and select which base layer to start with === Feeds === * Provide UI to access feeds: * KML feeds: * http://haiti.sahanafoundation.org/prod/gis/location.kml * http://haiti.sahanafoundation.org/prod/gis/location.kml?feature_class=Hospital * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.kml * Provide an easy way to select the Org by name * http://haiti.sahanafoundation.org/prod/or/office.kml * GeoRSS feeds: * http://haiti.sahanafoundation.org/prod/gis/location.georss * http://haiti.sahanafoundation.org/prod/gis/location.georss?feature_class=Hospital * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.georss * http://haiti.sahanafoundation.org/prod/or/office.georss * GPX feeds: * http://haiti.sahanafoundation.org/prod/gis/location.gpx * http://haiti.sahanafoundation.org/prod/gis/location.gpx?feature_class=Hospital * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.gpx * http://haiti.sahanafoundation.org/prod/or/office.gpx * KML Export * Include Marker? * bounds information - e.g. lat/long min/max to go in the metadata. this improves display of KML when opened in the like of GE and other apps. not required, but does improve display * Polygon support (currently uses Centroid) * GeoRSS Export * Polygon support (currently uses Centroid) * GPX Export * stick some extra info into - as auto GPS units what support bluetooth phones can recognise phone numbers and allow hands free calling * bounds information - e.g. lat/long min/max to go in the metadata. this improves display of GPX when opened in the like of GE and other apps. not required, but does improve display * Import * GPX * Bulk Uploader needs finishing * GeoRSS * KML === UI === * Separate out the Internal Features from External Features in !LayerSwitcher ([http://geoext.org/tutorials/layertree-tutorial.html#filtering GeoExt] skills) * {{{views/gis/map_viewing_client.html}}} +68 * ~~Add numZoomLevels=22 (or some higher number than the default 16 so can zoom in on high res imagery better~~ === !OpenLayers === * ~~[http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Layer/XYZ-js.html XYZ Layers]~~ * Generated JS seems OK, but layers aren't visible * XYZ layers verbatim from http://hypercube.telascience.org/haiti/uav.html work when entered as advanced JS layers * Cluster Strategy * Handle many Vectors (IE can't handle many more than 100) * http://openlayers.org/dev/examples/strategy-cluster.html * WFS Layers * WMS Capabilities Browser * http://dev.geoext.org/trunk/geoext/examples/wms-capabilities.html * Unzip KMZ layers * Image layers?
