  1. Geographicalinformation systemwithinreach ‘Current Issues In Water Supply And Sewage’ November 2013 Adam Vinković, Hrvoje Kelčec

  2. Introduction Local GovernmentUtility CompaniesEDC • IMAGIS development factors  quality-price ratio: • Information technologies evolution • Improvement in geodetic survey methods Geographicalinformationsystem withinreach

  3. Data • 1st stage – extracting existing technical documentation: • Manual • Digital • 2nd stage – data acquisition using geodetic surveys: • Global Positioning System (GPS) • Traditional survey methods • CROPOS (CROatianPositionig System) Geographicalinformationsystem withinreach

  4. CROatian POsitioning System (CROPOS) • Global Positioning System method (GPS) • Nationalnetwork of reference GNSS stations of the Republic of Croatia • Services: • DPS(Differentialpositioningservice ) • VPPS (High-precisionpositioningservice) • GPPS (Geodetic-precisionpositioningservice) • Efficient, fasterand more economicalcompared to traditionalsurveyingmethods • Real-time point data acqusition Geografski informacijski sustav nadohvat ruke

  5. Fieldsurvey • GPS survey of all visible pipeline system elements (y, x, h) • Underground object measurement: Possible to reach Manhole opening (object projection+ depth) • Impossible to reach • Object external appearance • (positioning estimation) • Object attributes (name, type, material, location, description, condition, note,...) • Object photograph Geographicalinformationsystem withinreach

  6. GIS – importingandprocessing survey data • via AutoCADMap • via IMAGIS web application • Exporting point coordinates to textual file • Editing textual file in textualeditor • Importing textual file into GIS within web application ‘Ordinal number; X-coordinate; Y-coordinate; Elevation; Code;Note' Geographicalinformationsystem withinreach

  7. IMAGIS modules • Input and edit attributes stored in database • Editing and drawing geometrical utility object • Table report of the selected objects • Linking external data (drawings, textual files, photos) and GIS objects • Map plotting of various dimensions and map descriptions • Spatial locating (toponym, cadastral parcel, business units, etc.) • Data search: analyzing objects based on SQL queries • Recording and analyzing system interventions • Real time investment maintenance and management • External base maps  DGUGeoportal, GoogleMaps (Google Street View), Bing Maps, OpenStreetMapi sl. • etc. Geographicalinformationsystem withinreach

  8. Conclusion • Modern geodetic survey methods significantly accelerate data acquisition • Numerous advantages of webGIS application IMAGIS • Processor speed and operating system don’t affect the quality GIS • Number of users is not limited • Internet / Intranet access and mobile device version • Compatibility with AutoCAD Map Geographicalinformationsystem withinreach
