Describe your current GIS capability/expertise


How to measure the level of my GIS? there is no university give graduate letter GIS to me, there not GIS training and seminars that I follow, there is no subjects in my class to explaining about GIS, and there are no measuring instruments give a standard level of my GIS.  In study I am focus learn about agriculture and botany, and I am never to dream can be GIS. At elementary school I don’t like geography study, the first blind map study (learning knowledge place area has not name place).

 I have skills use GPS and transfer GPS data using software Arcview3.3. Sometimes I transfer GPS data use cable data and without cable data. Some my friends for help me to make maps, but they have data with writing coordinates UTM, DMS and TM3 (projection national agrarian department). On the other hand, spatial data in my maps like as administration area, road network, river flow and other use geographic projected.

Then, UTM projection data on my converted using extensions projection utility wizard to change as geographic projection. The Projection geographic with structure format degrees-minutes-second (DMS) converted again using Microsoft Excel. The sum converted DMS in Excel become as structure format like degree coma degrees (dddd,dddd). But, for the Y coordinates or longitude coordinates must be given a minus sign (-) because my locate project below the equator. And when I am receive data with projection TM3, I use Transcoord for change to UTM or dddd,dddd projection be dddd,dddd, it’s a software product survey and mapping national departement (Indonesia).

For transfer the GPS data using data cable, usually GPS data contained data with extention gpx then I am converted to extention shp and kml using QuantumGIS 1.7. In managing data at Arcview3.3 I am usually use of extensions like ; 3D Analyst, add XY, add DMS coordinates, do google earth, graticules and measured grids, analys image, JPG image support spatial analysis and Xtools. And how to know make a map using the information above, more details can be viewed on my Youtube of GIS at address :

I am use google earth and put it on my blog at 
http://forumtataruang.blogspot.com  and I am use the Global Map II to download topographic data (SRTM) too. I am use ArcGIS 9.3 but not as good using in Arcview 3.3. On build web GIS, I can do make use mappetizer software but use the trial only.

I’ve created a map city of Jambi with very details, far as I know it’s the best, I often promote to government but no respond. GIS not familiar on government.  Besides making a map the city of Jambi, I also made a detailed map of Jambi Province.

My work flow in using GIS begin with input data from GPS or hard copy data (scanning), after data  in process into shp and then I find the right scale to size the paper is being used. After data on scale can be adjusted and then add the data supporting such as data administration area, road network, river flow and spatial data information its self. Besides making maps, I am also training for someone to making maps. Last training of using GPS mapping can be found at this web address;

Map is a complex picture, a lot of lines that overlap. Need art in managing the composition of color and spatial information. Drawing map do not like a kids picture, find harmony color between spatial data and attribute data information. This is my interest on making a layout maps. Use a font size according place on lay out map, more attributes  information to show, I am must be more  observant in arrange. The final map is display contained the value art and aesthetics.  Format data in making the map ever I am created like  format *.apr, *.shp, *.kml, etc.
 
I work using GIS as a free land surveyors, draftsman maps, GPS and ArcView trainer. In training I do not require payment and sometimes I am voluntary. I do aim for socialization of GIS, because my town live very little understand GIS and need GIS course get expensive cost. Then I am willing to coach GIS for free, so that GIS will easily known by public.
