LOJIC Online Map: An Inside Perspective by Brian Meyers, Jane Poole & Julie Price, LOJIC

LOJIC had built a suite of ArcIMS based map viewers over the last 10 years The time had come to upgrade to ArcGIS Server A migration plan was developed Several partners began to take responsibility for the applications LOJIC once hosted LOJIC was tasked with migrating three of the remaining applications: Standard Information Map, Geodetic Control & the Historical Imagery Viewer Background

3 into 1

Requirements Intuitive interface Easy to use Fast Clean layout Popup friendly Preserve existing layers and tools

Layout

Silverlight vs. HTML / Javascript Existing developer skill sets.NET shop Plugin penetration rate Browser compatibility Support: desktop & mobile Maintainability Looking ahead: The role of Rich Internet Applications (RIA) Framework

ESRI Javascript API 2.8 Dojo 1.6 Framework continued

Tools: Measure, Buffer & Print –Measure widget from ESRI –Custom Buffer –Custom Print Reports: Development, Parcel & General –Geoprocessing vs Server Object Extension (SOE) Searches: Address, Intersection, Parcel By Id –Geocoding VS Custom Tools Extend / reuse existing ESRI & LOJIC code when possible Write re-usable custom tools as necessary: client and server side

Cartography – Basics for Cached and Dynamic Layers Optimized or Simple Symbology Limit use of Maplex Limit use of Cartographic Representations Design for Scale Levels

Caches Think about Processing time to create the Cache Design for Scale Levels Optimized or Simple Symbology Limit use of Maplex Limit use of Cartographic Representations Create using File Geodatabases, Query using SDE Databases

Dynamic Layers Think about Drawing time to draw each layer Optimized or Simple Symbology Limit use of Maplex Limit use of Cartographic Representations Design for Scale Levels

Symbology and Labels – Analyze Map Errors – Cannot create.MSD Warnings – Slows drawing time but will create.MSD Information – May or may not slow drawing time but will create.MSD

Analyze Map

Cartography Objectives Street Map Cache – Compliments Esri Streets Base map Base Map Cache – Same Symbology as Plan/Topo 100 ft/200ft Map Series Dynamic Layers – Matches Symbology of former ArcIMS map when possible. Dynamic Layers – Must be readable against all Caches.

Lessons Learned Help: less is more Printing: users still need hard copies We upgraded: yes it is different than before Browser compatibility User feedback – be responsive Cache scales: users want more
