  1. Beginners Guide:Embed GIS Maps Tutorialand Walkthrough w/Examples How to Add GIS Maps to Your Webpages

  2. Agenda • Why Use Maps • Four Ingredients to a Map • Generate Your First Map • Embed Your Map in a Web Page • Customize Your Map • Position the Center of your Map • View Map Examples • Use Maps in SharePoint • Contacts

  3. Why Maps • Maps are better visually to show global, regional, geographic information • Maps give a quick visual of complex data • Maps are more appropriate for locations, distances, routes, and boundaries • Maps are easy and fun!

  4. With Maps, Indicate… • Distances • Example: How far is it between Brazil and West Africa? • Boundaries • Borders • Specific Locations • airports • weather stations • Status • Compliance to regulations • Progress toward goals

  5. Maps of ICAO-related Information • Flight Information Regions (FIR) • Search and Rescue (SAR) • Language Proficiency (LPR) • WGS-84 Status • Performance Based Navigation (PBN) • Aerodromes • Many more…

  6. About maps

  7. Four Ingredients to Your Map • The web browser, or how you view the map • Internet Explorer, Chrome, Firefox, Mozilla, etc. • The applet or what "holds" the map • Adobe Flash, or Java • The geoserver, or what creates the map • http://gis.icao.int • The html, or what connects it all together • The instructions of what to show, where

  8. How it Works

  9. Let’s Make a Map Your First (very Basic) Map

  10. First, Create and Save a Web Page • Start Notepad or text editor • Create basic HMTL – (copy code below) <head>My First Embedded Map</head><p><p> <body <iframe src="url will be here"</iframe> </body> • Save the file • Name it using double quotes • "myfirstmap.html" • Hint: Remember where you saved it!!

  11. Generate the Map

  12. Start with the Subject of the Map

  13. Locate GIS URL • Browse http://gis.icao.int to choose subject • Use the GIS Services Selector (dropdown) • Choose a map with "Needs Flash" as label • Follow link to map • Copy the URL • Highlight and right-mouse click, "copy" • Example with AIS-AIM Map • View walkthrough in next slides…

  14. Step 1: Select Map (need Flash) In this example, choose AIM transition Click on map labelled "need Flash ICAO AIS AIM"

  15. Step 2: View Map and Copy URL From the browser, verify the URL is http://gis.icao.int/aisaim/ Right Mouse Click and Copy URL (http://gis.icao.int/aisaim)

  16. Step 3: Paste URL into <body> • Note that the URL is surrounded with double quotes <head>My First Embedded Map</head><p><p> <body> <iframe src="http://gis.icao.int/aisaim/"</iframe> </body>

  17. Step 4: Save and Check the Results • In Notepad, choose File, Save File • Remember where you save it! • Change to your desktop • Double-click File "mymap.html" to • Open with your browser

  18. Results: Congratulations! It is your first embedded GIS Map! We will customize it now…

  19. Troubleshoot • Check that you have all brackets (< >) • Confirm that all open tags have close tags • Be sure to have quotation marks (" ") • Sometimes "smart quotes" (curly quotes) can be a problem so change to "straight quotes" • Verify correct URL in browser • http://gis.icao.int/aisaism should open a full map • Remove unnecessary spaces or line returns • Have someone check your work

  20. Customize Basic Map

  21. Your First Embedded Map is OK… • Your first map was … • A bit small • Difficult to read • Legend is missing or too big, covering map • Impossible to control zoom and positioning • So let’s customize it! • Start simple…

  22. Toggle the Scroll Bar • To disable vertical scroll bar, add Scrolling="no" <head> My First Embedded Map<p><p> </head> <body> <iframe frameborder="0" scrolling="no" src="http://gis.icao.int/aisaim/"</iframe> </body>

  23. Add/Remove Frame Border • There is a small border around the map, by default, which you can remove by adding frameborder="0" Example: <iframe frameborder="0" src=http://gis.icao.int/aisaim…

  24. Change the Map Size • Map Size is from two properties (in pixels) • Width and Height • Use width and height numbers….or… • Example: width="640" height="480" • Use width and height percentage • Example: width="50%"height="50%" • Experiment to see what is most appropriate for your map and the users screen resolution

  25. Size of Map – Graphic view width="640" height="480"

  26. Check Your Custom Map HTML Code Resulting Map <head> My First Embedded Map<p> <p> </head> <body> <iframe frameborder="0" width="640"height="480"src="http://gis.icao.int/aisaim/"</iframe> </body>

  27. Emphasize Particular Regions, Member States, etc. Set map Starting position

  28. Position the Starting Map Options • Focus the map center on a particular place… • Position the map with • Center and scale (zoom) or • Extent (four boundaries) • Find the coordinates we prepared: • By State • By Flight Information Region (FIR) • By Aerodrome • Or find your own…more on this later…

  29. Position Map Starting Point Center and Scale or level

  30. Position the Map: Center, Scale/Level • Center and Scale settings work together • The Center coordinates = center point of map • Scale and Level indicates "zoom" level • Think "altitude" from which you view map • Adjust center and scale or level to create map with the view you want. • See explanation and examples next slides

  31. Decrease the Scale (demo)

  32. Zoom Singapore with Scale Setting scale=550000 scale=2000000

  33. Zoom using Level • Level (like scale) works with Center= • Zoom out by decreasing Level • Zoom in by increasing Level • Example: Level=19 is "urban city neighborhood" • Experiment for best options for you

  34. Now, Center the Map By "State" • Previous examples • Berlin as center point • Singapore as center point • What is the center point of your map? • Global is default • ICAO Member State, FIR, or Aerodrome? • Now you know what it means to center the map, we need the coordinates to do it…

  35. Center Coordinates by State • Choose map subject (lpr, fir, aop, wgs-84, etc.) • Example: src="http://gis.icao.int/ICAOLPR?... • Find center coordinates in the spreadsheet • http://gis.icao.int/anpdownload/ICAOSTATEall.xlsx • Use figures in Longwebmer and Latwebmer • Example 1: Mexico as the CENTER point <iframe…...center=-11433849.06000000,2776929.6055451858"> </iframe> • Note: The first coordinate above is a “negative”

  36. Center Coordinates by FIR • Use src="http://gis.icao.int/FIRMSD? • Find center coordinates in the spreadsheet • http://gis.icao.int/anpdownload/ICAOFIRall.xlsx • Use column contents in LongUTM andLatUTM • Example 1: FIR Mexico <iframe…...center =-11397743.7580,2614106.8183"> </iframe> • Note: The first coordinate above is a “negative” <iframe frameborder="0" width="100%" height="600" src="http://gis.icao.int/firmsd?center=- 11397743.7580,2614106.8183&scale=5500000"></iframe>

  37. Example: Center FIR Mexico

  38. Position / Zoom by aerodrome

  39. Position and Zoom by Aerodrome • We have two types of Aerodrome coordinates • AOP - 1540 • Jeppesen • Use src="http://gis.icao.int/aop?... • Add longitude and latitude from spreadsheets available on line • See the examples that follow…

  40. Aerodrome – AOP 1540 • Use src="http://gis.icao.int/aop? • Find center coordinates in the spreadsheet • http://gis.icao.int/anpdownload/ICAOAOPallEX.xls • Use column contents in LongWeb andLatWeb • Example 1: Mexico Acapulco (MMAA) <iframe…...center =-11104553.35260000000,1892579.90270000000"> </iframe> • Note: The first coordinate above is a “negative” • See screen shot next page

  41. Example: Center Aerodrome MMAA <iframe width="100%" height="100%" src="http://gis.icao.int/aop?center=- 11104553.35260000000,1892579.90270000000&scale=55000"</iframe>

  42. Aerodrome - Jeppesen • Use src="http://gis.icao.int/aop? • Find center coordinates in the spreadsheet • http://gis.icao.int/anpdownload/ICAOAERODROMEall.xlsx • Use column contents in LongWeb andLatWeb • Example 1: Mexico "Benito Juarez" (MMMX) <iframe…...center =-11028634.39000000,2206387.19625111"> </iframe> • Note: The first coordinate above is a “negative” <iframe frameborder="0" width="100%" height="600" src="http://gis.icao.int/aop?center=- 11028634.39000000,2206387.19625111&scale=55000"></iframe>

  43. Example: Center Aerodrome MMMX

  44. Add Coordinates and Scale to Page • Add a "?" following the URL • center=coordinate1,coordinate2 no spaces • Add "&", then scale=number and close quote • Example for LPR in Singapore <iframe frameborder="0" scrolling="no" width="480" height="270" src="http://gis.icao.int/icaolpr/index.html?center=11555859.55335120,150475.31134858 &scale=550000"></iframe>

  45. Position Map Starting Point Map Start using "Extent" (rectangular area)

  46. Position Map: Extent • The second way to set the initial view or position of a map is to use extent • Extent uses four coordinates: • X axis min, • Y axis min, • X axis max, • Y axis max • Example: SE Asia Region <iframe frameborder="0" width="100%" height="600" src="http://gis.icao.int/firmsd/index.html?extent=9965000,-129000,14206000,2733000"></iframe>

  47. Extent Coordinates… X max, Y max X min, Y min

  48. Position using Extent: FIR SE Asia <iframe frameborder="0" width="100%" height="600" src="http://gis.icao.int/firmsd/index.html?extent=9965000,-129000,14206000,2733000"></iframe>

  49. Position Map: Custom Extent • Find extent coordinates using Extent Helper • http://resources.arcgis.com/en/help/flex-viewer/helpers/FlexViewer_ExtentHelper.html • Locate your map center point and zoom in or out to the 'altitude' you wish • Check the extent coordinates at the top • Use them in the html for the SRC tag • Remove spaces, add commas for correct syntax • Screen shot next page
