Transcription

1 Matthew Delano, LS Geospatial World Forum January 2017 Leveraging Geospatial Technology for Cadastral Surveys

2 Fit-for-Purpose Simple to start Can improve over time whenever necessary Meet the needs of people and environment

3 Characterized as follows: Flexible in data capture methods Inclusive to cover all tenure and all land Participatory use and ensure community support Affordable to establish, to operate and to use Reliable information is authoritative and up-to-date Attainable within adequate time and budget Upgradable for incremental improvement

4 Transform the Way the World Works Rev. US$2.4Billion; 8,000 employees Founded in 1978, headquartered in Sunnyvale, Ca Agriculture Heavy Civil Construction Building Construction Geospatial Transportation & Logistics Rail Environmental & Waste Water Utilities Electric Utilities Mining Forestry Field Service Oil, Gas & Chemical OEM & Consumer Government

5 Trimble Solutions Improving the workflows for cadastre and land administration

6 How 50% faster Data collection faster (Intelligent Integrated Surveying) QA already in field, no site revisit Process integration (task management) Disrupt traditional workflows (remove steps: postprocessing, network adjustment, most of CAD work,...) Processing / CAD functionality move to the cloud (Trimble Connect)..

7 Leverage imaging technology and resources

8 Data Collection - Imagery flexible inclusive Satellite image / digital ortho photo Unmanned Aerial Vehicle

9 Imagery Processing flexible inclusive Orthophoto, Digitization Trimble ecognition

10 ecognition Essentials: Make Sense Out of Images Mass Data Analysis Create GIS-ready Layers Tree Map (Vector) Impervious Map (Vector) Land Cover Map (Vector) Elevation Data (Raster) Automated Interpretation Image Data (Raster) Manual Interpretation Real World

11 Definition of Parcel Boundaries - Rural Orthophoto with fields Fields with boundaries

12 Definition of Parcel Boundaries - Urban orthophoto with village village with boundaries

13 Leverage appropriate geodetic technology

14 Geodetic Framework RTX Service Centimeter everywhere. upgradeable CORS Centimeter in seconds.

15 Correction Options RTK < 1 / < 1.0 cm VRS < 1 / < 1.0 cm RTX

16 Leverage work management technology

17 Process Integration (work mgt.) Select work area

18 Process Integration (work mgt.) Assign to crew

19 Process Integration (work mgt.) notification Receive new tasks

20 Leverage appropriate technology & accuracy

21 Penmap

22 Orthophotos & Cadastral Data Load detailed background imagery and data (DWG, CSV, SHP)

23

24 Leverage Process Integration QA in the field

25 GIS Attribution Modify and update Parcel information and attribution

26 Forms, Interviews, Questionnaires GIS attribution with forms, images and text entry

27 Markup, Annotate, Redlining

28 Verification, Adjustment, Validation flexible

29 Penmap: Visual and Easy to Use Surveying, GIS and CAD workflow capable Flexible configurations for accuracy and equipment Manufacturer independent

30 Leverage Process Integration eliminate steps

31 Current (Cadastral) Process 1. Cadastral map from Cadastre (DWG, GML,...) 2. Preparation for Field (create point files, print maps...) 3. Field Work (Feature coding, manual sketching, notes...) 4. Data processing 5. MOVE3 adjustment 6. Quality Control 7. Drawing (CAD) 8. Deliverable (DWG, PDF, MOVE3 Reports etc.)

32 New (Cadastral) Process 1. Cadastral map from Cadastre (DWG, PDOK GML) 2. Field Work in Penmap incl. MOVE3 & Quality Control (3. CAD) 4. Deliverable (DWG, MOVE3 Reports, PDF etc.) Up to 50% Time savings
