Comparison of villageQGIS and QGISUsing villageQGIS software: (e.g. 3 clicks)For each feature of each layer (of type line or polygon): Constructing lines and polygons from GPS point data: - specify way points to join as a string e.g. “209-213, 218, 221-224” - visually verify correctness of boundary points & joined line/polygon Converting lines and polygons into GIS features: - select layer name from a list box e.g. “streams” or “farms” - fill resulting attribute form with data from questionnaireUsing QGIS software: (e.g. at least 17 clicks)For each feature of each layer (of type line or polygon): - Select desired feature and select option to add new a feature - For each GPS point: (e.g. 209,210,211,212,213,218,221,222,224”) - locate it on the screen, using find button or appropriate label option - draw a line connecting it to previous point - fill resulting attribute form with data from questionnaire - Save

  • 43. Outline1. Need for Participatory GIS Case Study of a South Indian Village2. Software Development Design and Implementation Field Trials Iterative Development3. Conclusions
  • 44. Iterative Development of GISFor monitoring & visualization; Enforces participation & field visits
  • 45. Providing Indian Language InterfaceSimplified User Interface (UI): For facilitating participation1. Text display in Indian languages:- static text (such as tooltip and button labels)-dynamic text (such as user entered data )2. Attribute data as audio output3. Help/instructions using audio and/or video4. ‘Text-free UI’ (as far as possible) E.g. User entered text in Indian languages
  • 46. Porting to Handhelds for On-Site Map Preparation and AnalysisMap preparation as One-step On-site process: On-site Map analysis:1. Following map preparation steps can be combined: 1. On-site map analysis for a. Spatial data gathering using GPS better participatory planning, b. Attribute data gathering using PDA/questionnaires implementation and b. Preparating maps using ‘Gram Panchyat QGIS’ monitoring becomes possible.2. This facilitates transparent verification and correction. If internet connection is3. Created/updated map features can immediately be available, this can be an onlinereplicated to a central map server (e.g. open source UMN MapServer) process through web client;through internet, facilitating social and official monitoring. else an offline process using last available data.Examples:1. Samsung Galaxy Tablet 2. Akaash Tablet Rs. 28,000 /- Rs. 2,500 /- 0.565 kg 0.350 kg 10.1 touch screen 7 screen 9 hours battery 2-3 hrs battery Android 3.1 OS 3. Samsung N100 Netbook Rs. 12,290 /- 1.03 kg 10.1 screen 5+ hours battery Ubuntu OS
  • 47. Mobile SMS based Basic Map Updating and QueryingMap updating: Map querying:1. Send updated attribute 1. Send query as structured SMS to central server and receive basic attribute datadata as structured SMS to (e.g. Basic measurement and expenditure details of such-and-such work) (‘pull’)central server (e.g 2. Send SMS alerts about map updates, etc to registered users such as concernedcompleted works) beneficiaries, officers, etc (‘push’)
  • 48. Browser based Data Entry, Viewing & AdministrationOpen Source UMN Map Server & Adempiere ERP server Drill down to farms/sub-polts & households Upload & download (push & pull) using mobile SMS,tablets (open source Android OS) & netbooks (Ubuntu OS) Drill down up to individual vouchers

  • 54. TutorialInput data:GPS and Questionnaire data about: - a stream and a reservoir - farms under that reservoir, etcTask:Create a GIS map: - first using villageQGIS - then using QGIS (or Map Windows GIS)Compare the time taken and map accuracy
  • 55. ArcView 3.1 GIS-based Scripts for Automated Map GenerationRun a script and specify location of imported GPS & Questionnaire files
  • 56. Using ArcView 3.1 ScriptsEnter attribute data from each questionnaire table into an Excel file(e.g. c:av_datagps_pdawell_points.txt) and convert it into a tab-delimited text file 1. Run ARCVIEW3.1SETUP.EXE from CD Default directory for installation is C:ESRI. 2. Copy av_data directory from CD to C: 3. Run c:av_dataprojectproj1.apr 4. Run ‘0_main’ script and specify location of imported GPS and PDA files: ‘proj1.apr’ window‘Scripts’ icon‘0_main’ script‘Run’ button‘Select Mapsource File’=c:av_datagps_pdamapsource.txt’Select Attribute Files’=bw_points.txt;fm_polygons.txt;sm_lines.txt
  • 57. Preparing Maps using ArcView 3.1 GIS without Scripts1. For each point theme: Based on its questionnaire table file: 1. Create a new ArcView table 2. For each record/feature: Copy Name/Long/Lat of appropriate Waypoint from mapsource.txt into the new ArcView table 3. Create a new Event Theme using the new ArcView table 4. Join new table with questionnaire table (after converting it into dBASE format)2. For each line (or polygon) theme: Based on its questionnaire table file: 1. Create a new Theme with shape = line (or polygon) 2. For each record/feature:  recursive 1. Create a new ArcView table 2. Copy Long/Lat of appropriate Trackpoints from mapsource.txt into the new ArcView table 3. Create Event Theme using the new ArcView Table 4. Create new feature by joining these points  recursive 3. Join Attribute table of new theme with questionnaire table file (after converting it into dBASE format)
