This is an advanced project. Two different imagery sources must be used in order to evaluate changes. Using JOSM editor is highly recommended to be able to quickly switch between layers and more easily input the advanced tags.
Tip: You can easily show or hide imagery layers in JOSM by pressing alt+NUMBER, where NUMBER is the number of the layer, starting with 1 at the bottom of the list and counting up from there, so alt+3 will show/hide the third layer from the bottom. </div>
You will encounter three possible scenarios when updating IDP sites:
IDP settlements and IDP tents both share the same tagging scheme
###idp:camp_site=spontaneous_camp ###damage:event=nepal_earthquake_2015
###idp:status_yyyymmdd={new,increased,decreased, or empty}
####ex: ####idp:status_20150427=new ####idp:status_20150503=decreased
###idp:source_yyyymmdd={add appropriate source}
####ex: ####idp:source_20150427=CNES, Airbus DS ####idp:source_20150503=GeoEye1 DigitalGlobe
####You can see in the examples above you have two idp:source tags because you used two imagery source to evaluate the change in the IDP site. You also have two idp:status tags to record the status at two times.
Impromptu IDP settlements in urban areas are located in non build-up portions of a city. They can usually be identified by bright orange or blue tents arranged in a non linear fashion within open areas. Open areas usually consist of parks, school yards, athletic fields, or other small open areas in a city.
An Area IDP settlement will usually have 5 or more tents. Create an area feature and trace the extent of the entire open area, this will allow for calculations of IDP space and can assist with the overall response.
IDP tents in urban areas are located in non built-up portions of a city. They can usually be identified by one large bright orange, blue, or white tent arranged in a small open area.
Single tents are located in small areas not large enough to hold more than one or two total tents. There often isn’t much surrounding open area, in these cases create an area feature and just trace the outline of the tent. Total tent area can be used to estimate the number of of IDPs, which will assist with the overall response.
