Osm Training Ht10 Hot English Version

  1. 1. Intro to OSM Open Street Map is a web project to create a free and open map of the entire world, built entirely from volunteers surveying with GPS, digitizing aerial imagery, and collecting and liberating existing public sources of geographic data. The goals of this training are to: 1 – Familiarize participants with the basics concepts of OSM 2 – Give introduction to field data collection/ground-truthing using GPS, Walking Papers and Questionnaires 3 – Provide instruction on how to edit data using JOSM 4 – Give a basic understanding of the OSM data model 5 – Provide generic instruction on how to use OSM data in GIS map production (ESRI & QGIS) – GISers only-
  2. 2. GPS and Walking Papers Combined, GPS and Walking Papers can be used for rapid surveying and ground truthing. Walking Papers allow users to print out small sections of the OSM map. In the field, these paper maps can be used to draw new features, annotate existing data, and take notes that will help with the import of GPS data. Icons in each of the corners and a unique code for each Walking Paper let users scan the paper and upload to OSM so the notes can be viewed in an editing environment. Very basic GPS devices will work. We're only looking at collecting points and tracks.
  3. 3.

  4. 4. JOSM and Potlach JOSM and Potlach are the two main editors used for creating and modifying OSM data. Potlach is a simple web interface, accessible to users on the OpenStreetMap website. JOSM is a more advanced tool, is a Java application so doesn't require consistent internet access and can run on any operating system.
  5. 5. Go Collect Data
  6. 6. Surveying plan/ tactics = Objective = •Aim •Features to collect •Area of Interest: = Support Docs = * Data structure ** data model (UNSDIT, DTM) ** OSM MapFeatures ** Humanitarian Data Model bridging between data models and OSM Map features * Questionnaires * Presets for data editing * tech: OSM platform = Organisation = * Survey zones * Teams (2/3) * Combined use of surveying tools and techniques: ** GPS: navigation and points + tracks marking. ** Walking papers: navigation + annotation (geometry + attributes) ** Questionnaires
  7. 7. GPS Babel To get data off your GPS and into a format usable by JOSM, we use a free software called GPS Babel. Connect your GPS device to your computer using the USB cable, select Device and Garmin serial/USB protocol as an input format. Then choose GPX/XML as your output format, name your file, and hit “let's go.” GPS Babel can also convert GPS data KML, CSV and other formats.
  8. 8. Starting JOSM and Adding Data Starting JOSM with additional memory (Optional): Command prompt for JOSM installed on the desktop: C:>WindowsSystem32java.exe -jar -Xmx512M "C:UsersuserDesktopjosm-tested.jar" Adding Your GPX data: In JOSM, go to “File->Open” and select the GPX file you just created. Adding Existing OSM data: You'll want to start with the data already exists in OSM and have your editing strategy be based on adding new features or modifying those that are already there. To download data directly from the server, zoom to the bounds of your GPS data in the main browser, then go to “File->Download from OSM.” Your extents will be pre- highlighted in pink. Click download, making sure the “Download as new layer” box is checked. If you already have OSM data at hand that you want to use, you can open it as you did with the GPX data already and it will appear as a new layer.
  9. 9. Walking Papers When you've collected your Walking Papers data, you need to scan it and save the resulting image on your computer. Go to: and follow the instructions there. Once uploaded, the site will give you a unique URL for your scan. Go to JOSM, and select Walking Papers from the menu, choose “Scanned Map,” enter the URL of your scan and press “OK.” You will now see your scan alongside the existing OSM data and your GPS tracks.
  10. 10. Editing in JOSM
  11. 11. Relevant tags/features OSM attribute data is stored in key:value pairs. The tagging system is completely flexible, new keys and possible values can be added ad hoc. But in order to ensure compatibility between data, it's best practice to use existing tags where possible. The full list of recommended tags can be found on the OSM wiki at: Details on the Humanitarian Data Model and the JOSM presets we've built to accompany it can be found at: For the purposes of today's session, here are some suggested tags to use when adding your data: Key Possible Values Area yes Building container, tent, hangar, tent, yes Amenity bathroom, parking lot, fountain, school, health clinic Highway pedestrian, service, secondary Surface gravel, dirt, concrete, paved, unpaved Source Walking Papers/GPS
  12. 12. Using OSM resources in ArcGIS and QGIS This module meant to GIS practitioners will cover the following: Loading OSM data (shp, wfs, postres-postgis table, wms) Exploring OSM data Editing OSM data Visualizing OSM data Rendering OSM data (basic & more advanced cartography)
  13. 13. Humanitarian OpenStreetMap Team (HOT) Core Mission - connecting point between humanitarian and open mapping communities - remote data creation during crisis - collection and organization of existing data sources - deployments to the field possible - distribution point for free data Advocacy, Training and Outreach - mapping parties - speaking, writing, meetings in humanitarian and United Nations technical communities Thinking and Design - promotion of crowd-sourcing and simple web standards for data sharing - technical improvements to OSM and OSGeo in response to field requirements (offline support, verification, format adaptors, multi-master sync..)
