Wiki-NittyG: title?

==Title?==
Wasn't sure what title to add. Right now there is no community, and it's just myself, and this really serves as an introduction to all the efforts. Perhaps I should change the intro, or keep it the same and change the title to being singular. Feel free to just go ahead and do that, creating a new page with a different title, copy-pasting everything to the new page, and have this page perhaps redirect to the one you create.

Open Online Polygon Mapping Communities

A community needs to be created where one can create and represent polygons, similar to how people can edit line features with openstreetmap (OSM, [http://www.openstreetmap.org]. There are several efforts to allow people to create and manipulate polygons, which are currently being inventoried below.

There would be great power in an online community around polygons. For example, a user could enter a year, such as "1900" and see the way the world was then, as well as animate historical changes and events (see Centennia as an example, 1000 years of European history and 10,000 border changes [http://www.youtube.com/watch?v=oxrXiO0zcVw&feature=related]). Also, a community could exist around different statistics, such as population density, which could be visualized in darker shades of red (see ''Gridded Population of the World''[http://sedac.ciesin.columbia.edu/gpw/index.jsp]).
I can then edit a map, changing and adding polygons, and their colors and metadata. I should also be able to view areas by, say, population density and other statistics.

=List of Online Polygon Mapping Tools and Communities=

There are several tools that are available to map polygons online, which range from proprietary, to semi-proprietary and based on open source tools, to completely open source. Most of the open source tools are built on functions that exist in OpenLayers.

==Open Source==
*'''OpenLayers'''. Demo [http://openlayers.org/dev/examples/vector-formats.html]

*'''OpenMoose'''. Demo [http://www.geomoose.org/demo/geomoose2-webmercator/geomoose.html]. Uses OpenLayers.

*'''OpenStreetMap'''. An explanation of how to create polygons, such as buildings [http://help.openstreetmap.org/questions/2044/digitizing-buildings-in-potlatch]. A user closes a polygon by clicking the first point in a polygon to close it, then adding choosing from a dropdown menu a polygon feature such as "building".

===WMS-T Support===

Web Map Server - Time (WMS-T) is a standard that allows a WMS server to provide support to temporal requests. This is done by providing a TIME parameter with a time value in the request. Overview of projects using WMS-T: [http://underdark.wordpress.com/2011/06/10/wms-t-support-in-geoserver-and-mapserver/]

*'''GeoServer'''. Blog entry about WMS-T [http://geo-solutions.blogspot.com/2011/06/time-and-elevation-support-in-geoserver.html].

*'''MapServer'''. WMS-T page [http://mapserver.org/ogc/wms_time.html].

==Semi-Proprietary==
*'''GeoCommons''' [http://geocommons.com/]. Communities can collaborate online around maps. Users can simply upload a spreadsheet with names of entities (countries, zip codes, etc), with associated numbers, and a map is automatically generated. Can upload KMLs, and see animations.

==Proprietary==
*'''Click2Map''' [http://www.click2map.com/free_map_editor]: Customers can buy the tools to put on their own servers. A free demo is online. Users can create a polygon, and a dialog pops up automatically, in which a user can easily add the metadata, including the name and color and line thickness and description.

==About Me==

Nitin Gadia.
Ames, Iowa, USA

I'm interested in everything, geospatial only one of them - mostly because of how it can display everything... geospatially.

==My Geospatial Desires==

To put it broadly, I want to help create something where one can create and represent polygons, like how openstreetmap (OSM, [http://www.openstreetmap.org]) can edit line features, like roads.

Basically, I'm envisioning a separate site where someone can add polygons such as historical nations, and then be able to animate them. I should be able to type in, say, "1900" and see the way the world was then. I can then edit a map, changing and adding polygons, and their colors and metadata. I should also be able to view areas by, say, population density and other statistics.

===My work, examples===

I want to help create an open historical map of the world. Check out the work I've done so far (scroll down to ''Geographic Information Systems'') [http://www.thenittygritty.org/intheworks.html]

Also, check this out - a historical map of Europe from the last 1000 years. Over 10,000 border changes [http://www.youtube.com/watch?v=oxrXiO0zcVw&feature=related]

==My Geospatial Story==

Years ago, I saw Encarta's Virtual atlas, the first time I saw a computer map of the whole world that I could explore. As I would explore visual statistics, my mind would race about how much you could display. I thought of how great it would be if you could, say, type in a year, and see the way the world was at the time, and animate it to see how the borders changed. Then came Google Earth, which eventually had an animation function. I saw someone describe seeing google earth to the first time they saw an internet browser - a wealth of possibility. Not long ago I saw a TED video where someone showed the openstreetmap effort following the earthquake in Haiti [http://www.ted.com/talks/lang/eng/tim_berners_lee_the_year_open_data_went_worldwide.html]. Again, I got excited, and started to dabble in the project. I made a basic animation for historical maps using ArcGIS, which could be exported to Google Earth. As of now, I am trying to see how to make this happen to its fullest extent. I am in the exploration phase - seeing what projects there are, and how I can be a part of them, or make a new one if necessary, combining the elements of others.
