    27. Other types of web maps <ul><ul><li>Distributed web maps Maps are created from distributed data sources. The interface of the web mapping system provides a method to access maps on other servers. </li></ul></ul><ul><ul><ul><li>http://www.openlayers.org/ </li></ul></ul></ul><ul><ul><li>Real time web maps </li></ul></ul><ul><ul><ul><li>Real time maps show the situation of a phenomena as it is occurring. http://science.nasa.gov/Realtime/jtrack/3d/JTrack3D.html </li></ul></ul></ul>
    28. <ul><ul><li>Open, reusable web maps </li></ul></ul><ul><ul><ul><li>Web maps in this category are usually more complex web mapping systems that offer APIs for reuse in other people's web pages and products. An example for such a system with an API for reuse is Google Maps. </li></ul></ul></ul><ul><ul><ul><ul><li>http://developer.yahoo.com/maps/flash/index.html </li></ul></ul></ul></ul>
    29. Evolution: Transferring of Data <ul><ul><li>The difference lies in how data is streamed from the provider to the user Over the Internet </li></ul></ul>
    30.  
    31. Data Components of Web Maps
    32. Vector
    33. Raster
    34. Vector VS Raster <ul><ul><li>Neither is better </li></ul></ul><ul><ul><li>The data you utilize depends on the purpose of the application </li></ul></ul>
    35. Vector VS Raster <ul><ul><li>Vector data is an interpretation of the natural world </li></ul></ul><ul><ul><li>Raster data is an actual representation of the natural world at a moment in time </li></ul></ul>
    36. Primary VS Secondary Data <ul><ul><li>Primary Data </li></ul></ul><ul><ul><ul><li>Data that the application is concerned about </li></ul></ul></ul><ul><ul><ul><li>Main theme of the application </li></ul></ul></ul><ul><ul><li>Photos </li></ul></ul><ul><ul><ul><li>http://www.iceburnslair.com/mapper/lv-night/GMap.php </li></ul></ul></ul>
    37. Primary VS Secondary Data <ul><ul><li>Basemap Data </li></ul></ul><ul><ul><ul><li>Supporting spatial data used to contextualize the mapping application's theme. </li></ul></ul></ul><ul><ul><ul><li>Basemap </li></ul></ul></ul><ul><ul><ul><ul><li>http://www.openstreetmap.org </li></ul></ul></ul></ul>
    38. Summary <ul><ul><li>Web maps require </li></ul></ul><ul><ul><ul><li>Spatial Data </li></ul></ul></ul><ul><ul><ul><li>Software package to serve up the spatial data </li></ul></ul></ul><ul><ul><ul><li>A general plan as to the purpose of the application </li></ul></ul></ul>
