Answer
<googlemap version="0.9" lat="62.816274" lon="27.718506" type="map" zoom="9"> 6#B2758BC5 62.968957, 27.712326 62.97395, 27.750092 62.951476, 27.79541 62.965836, 27.826996 62.90898, 27.902527 62.858905, 27.951965 62.754726, 28.048096 62.715721, 27.891541 62.708166, 27.781677 62.701868, 27.671814 62.718239, 27.509766 62.781119, 27.408142 62.841316, 27.305832 62.923986, 27.301025 62.975198, 27.424622 62.971453, 27.526245 62.97395, 27.692413 62.968645, 27.70752 </googlemap>
Define specific land boundary for Kuopio as it shows in the above map.In order to find actual land use and boundary in Urgenche, We used Google map by random sampling. In those 6 cities as are shows in the following table.
We looked for simple software such as GeoTIFF, NITF, JPEG 2000, ECW (file format), MrSID, HDF, and NetCDF to detect land in the Urgenche. as far as all of them was quiet professional software we decide to print the map and measure different land by hand and scale.
Obs | City | Green area | Urben area | Water area | Other area |
1 | Kuopio | 70% | 10% | 20% | |
2 | Stuttgart | 40% | 40% | 10% | 10% |
3 | Basel | 5% | 80% | 10% | 5% |
4 | Rotterdam | 15% | 55% | 20% | 10% |
5 | Thessaloniki | 5% | 80% | 15% | |
6 | Xi'an | 10% | 3% | 87% | |
7 | Suzhou | 5% | 35% | 15% | 45% |
To know the accurate percentage of the land and water, we used the map for each city. We print the colorful printing and the cut the land and water for each city. We used Google map, in the printing version of the Google map it’s not possible to differentiate green area and building. We weight water and land with the digital balance. The results are as follows.
Out f 7 city we only evaluated 3 cities such as Kuopio, Basel and Thessaloniki. For bigger cities particularly for Xi'an and Suzhou the Google map data is not reliable.
Obs | City | wight of land area | wight of water area | % land | % water |
1 | Kuopio | 0,9 | 0,9 | 50 | 50 |
2 | Basel | 0,03 | 0,52 | 5,454545455 | 94,54545455 |
3 | Thessaloniki | 0,58 | 1,28 | 31,1827957 | 68,8172043 |
Obs | City | Green area | Building area | Water area |
1 | Kuopio | 10% | 72% | 18% |
2 | Kuopio | 25% | 75% | |
3 | Kuopio | 36% | 52% | 12% |
4 | Kuopio | 20% | 80% | |
5 | Kuopio | 46% | 54% | |
6 | Kuopio | 36% | 52% | 12% |
7 | Kuopio | 36% | 64% | |
8 | Kuopio | 72% | 28% | |
9 | Kuopio | 64% | 12% | 24% |
10 | 36% | 52% | 12% |
