Why Look at Other Maps

Map Alternatives Workshop


Discussions topics

Discussions Topics

  • Map Technology used

    • ITN required use of FDOT provided “shape files” (limits available tools/solutions)

    • Browser based solution:

      • Facilitates “updates”

      • Highly portable (i.e. any computer with a browser) and flexible (i.e. easy to add users by simply providing access to “server”)

  • Current issues:

    • SVG used as “drawing” tool

    • “Look and feel”

    • Functionality

Map Alternatives Workshop


Map implementation approaches

Map Implementation Approaches

  • Workstation approach:

    • Map data and application INSTALLED on workstation

  • Server approach:

    • Map data and image generation performed on a server

Map Alternatives Workshop


Map implementation approaches continued

Map Implementation Approaches: continued

Alternative server implementation: return more than an image

SunGuideSM Approach: hybrid that process “map” data at the local workstation

Map Alternatives Workshop


Svg technology used to implement the sunguide sm map

SVG Technology Used to Implement the SunGuideSM Map

  • Map is rendered using JavaScript and SVG (Scalable Vector Graphics)

  • Background on SVG:

    • Is NOT a vendor specific product

    • Is a W3C standard

    • 2D graphics

    • Mobile versions available

  • SVG plug-ins:

    • Adobe used in SG deployments

      • Adobe dropping support 1/08

    • Firefox (mozilla.org)

    • See www.svgi.org

Why is this being discussed

Why is this being discussed?

  • Questions about SunGuideSM map “performance”:

    • Performance issues are based on XML messages being processed by GUI (and not map rendering)

    • GUI enhancement in process to address parsing issue

Map Alternatives Workshop


Gui performance enhancement currently being implemented

GUI Performance Enhancement Currently Being Implemented

Map Alternatives Workshop


Moving forward look at map improvements

Moving Forward:Look at Map Improvements

  • New functionality being requested of the map as deployments utilize the SunGuideSM map

  • Questions to be considered:

    • What additional functionality is required:

      • Street names? Everywhere or just around instrumented roadway segments?

      • Better looking “eye candy”?

    • Should the Operator “base” map (the map in the control center) be the same as provided on an Internet web site?

    • How often should the base map be updated?

    • Should FDOT control the “map services” (i.e. the creation of maps)?

Map Alternatives Workshop


Map creation options summary

Map Creation Options: Summary

  • Workstation based Map (e.g. ESRI GIS tools)

  • Server based map (e.g. Google Maps)

  • SunGuideSM (combination of both of the above)

SunGuideSM Map – What it Does

Map Alternatives Workshop


Sunguide sm map summary of existing requirements

SunGuideSM Map: Summary of Existing Requirements

  • Map shall display:

    • Congestion (color coded to indicate conditions)

    • Incidents (use color, flash, audio, icons to indicate status)

    • Device (e.g. DMS, camera, detectors) locations (use color to indicate status)

  • Map shall support:

    • Manual creation of incidents

    • Selection of alternate map views

  • General requirements:

    • Map source shall be shape files

    • SVG (Scalable Vector Graphics based)

    • Color choices shall be user selectable

    • Internet map must meet OIS guidelines for Internet sites

Compiled Responses to Map Questions

Map Alternatives Workshop


Questions posed by alternative map technologies white paper

Questions Posed by Alternative Map Technologies White Paper

  • White paper posed the following:

    • Source for dynamic data?

    • Fidelity of data: what level of data is needed?

    • Data updates: how often are made updates required?

    • Operations map versus “consumer” map: does the map solution need to be the same for operations versus the consumer (Internet) map?

    • Is FDOT willing to rely on a third-party for real-time map data?

    • Is FDOT willing to accept a “transaction based” map server?

    • Security of map server?

  • FDOT CO solicited feedback on each question

  • “Bonus” question at the end

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Source for dynamic data? What will be the source for data for the map? The SunGuideSM software has a Center-to-Center component that provides the data necessary for a robust traffic conditions map. The use of a standard interface would assure portability of the mapping application to multiple Districts (i.e. a “generic” web site that could be re-used many times). This more an Internet Web Site question.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t1

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Fidelity of data: what level of data is needed? For example, is the data available from Dynamap acceptable or is the type of data from a MapPoint/Google required?

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t2

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Data updates: how often are made updates required? Each vendor of map data has a different update schedule, FDOT needs to evaluate how often they require a map “refresh” and whether or not the vendor provides the frequency required.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t3

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Operations map versus “consumer” map: does the map solution need to be the same for operations versus the consumer (Internet) map? The map needs for control center applications are different than a simple graphical map that is presented to travelers.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t4

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Is FDOT willing to rely on a third-party for real-time map data? If an external server is providing map images, FDOT will be completely at the mercy of the health of that server for its own operations.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t5

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Is FDOT willing to accept a “transaction based” map server? Several major products have transaction pricing established. Within the industry, there is lot a of speculation that the products currently free (e.g. Google Maps) are likely to switch to a transaction based cost system or the number of advertisements will increase.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t6

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Security of map server? If the solution is based on an outside map server (e.g. Google), what might happen if network connectivity were lost during an emergency event? This could include massive power failures (hurricane related) or simply a failed network connection from the Internet provider. Having the map hosted outside the TMC places a dependency on external Internet providers for access to the map.

Map Alternatives Workshop


Questions posed by alternative map technologies white paper con t7

Questions Posed by Alternative Map Technologies White Paper – con’t

  • Bonus question:

    • Would FDOT be willing to switch the SunGuideSM user interface (Map and all GUI components to a “Windows based” application?

  • Notes:

    • Much of the C# working being done in the GUI enhancement would be reusable

    • Implies that software would need to be installed on EACH workstation accessing SunGuideSM.

Recommendations

Recommendations

  • Do not select a map tool until desired functionality is captured

  • “Needs” for map be captured:

    • Write as requirements

    • Prioritize and establish consensus

  • Evaluate implementation alternatives:

    • Evaluate implementation options

    • Evaluate development costs

    • Evaluate deployment / maintenance / usage costs
