Conference Note: Cartographic Symposium - Portland State U Nov 3, 2015
I. Key Note: James Meacham University of Oregon - Dept of Geography
Infographic Lab - http://infographics.uoregon.edu/projects/
Talked about workflow for Visualizing Data with example from Atlas of Wildlife Migration (http://infographics.uoregon.edu/projects/atlas-of-wildlife-migration/)
1. Data Collection --> Developing storyline:Markup iwth white board (inital mockup)/conceptialization -->Collaborative Design (example of working w/ biologist, dash-line showing two overlap direction) --> Outreach to social media/newspaper. Finished product: http://migrationinitiative.org/content/atlas
Take away - using whiteboard to draw up initial ideas/product and collaborate with subject matter experts.
Potential use for WTD: infographic of each pipe segment, profile DSM, landuse similar to last page bottom graphics from the report.
II. Paper Map to Slippy Map
Adam Wilbert - CartoGaia, Bellingham, WA
Slippy Map = "User driven multi-scale panable map". He talked about paper map vs. web map. Even with advatange of high zoom-in capability of web map, actual view port (screen size) determins the quality viewing. Paper map still has the better viewable quality. Paper map has the quality of showing multi-scale level. PDF map can be use zoomify tool in PhotoShop which has nice quality, smooth transitioning but the technoogy is based on Adobe Flash, doesn't work on mobile and dead-end technology.
He suggested alternate technology called maptiler http://www.maptiler.com/. Looks very promising and will look into converting detail map into PDF then tile them out to view through webserver then onto browser. Doesn't have any interactivity but might serve the viewer appropriately.
III. Transit System Map - Trimet.
Grant Humphraise
Purpose: Illustrate when and how to interact with other items. Understand inherent limiation.
Good resource to view other system maps : Human Transit blog- what makes good transit map http://www.humantransit.org/
Difficulties of system map
1.Scale
2. generalization (simplfication), not friend of cartographer. main point is to reduce file size. In ArcGIS, use Paek method (higher tolerance makes it more different) in Toolbox (around edge) vs Bezier Interpolation.
3. Geographic accuracy vs utility : making maps easier to read and convey purpose.
4. Merge divided road (ArcGIS cartography toolbox): Skeleton tool written by Migurski.
5. OVerlapping Routes - Manual work - can work to offset. Using offset technique is manual, no automatic solution (using Tracing Edit tool in ArcGIS is good tool). Calculate offset distance - offset in map unit.
6. Effective use of line color & weight (old one had 7 colors, too many).
IV. Oregon Incident Response.
They've adopted new standard for displaying emergency respond symbology. In order to be effective crisis mapping, able to view map without legend, don't need to consult legend and able to discern information over glance. Communicate very quickly various information.
[WTD facilities emergency hazard and critical map: Include following features in-addtion to existing facility/hazard features: Fire stations, police, hosptial, school, parks, large box store (costco, target, walmart). Create very detail maps, streets, label with names...then use Maptiler.com to create tile version to be posted in the webserver to share with other jurisdiction.]
