1 Guidelines for field-based application development

Interests…Guidelines for field-basedapplication development• Experience in relevant technologies:• ArcPad field-based applicationdevelopment• Visual Basic programming language• 4 Projects in 5 years for 3 differentorganisationsAuthored by: Andrew Hansford, Lex Chalmers, and Oliver Sangsterandrew.hansford@ew.govt.nz12Why Standardise Field-basedapplications?• Use of universal locational information• Common principles and practices• Options to use emerging mobiletechnologiesStable field-based system• ArcPad is widely-used applicationAbility to handle a variety of field-basedapplications• Solid programming environment (HTML)Ability to embed with Visual Basic and Java Script• Library support base and community34Brief History of Time…STEMs• Projects1. Standard Tree Evaluation Method (STEMs) –2005 (redeveloped 2009)2. Weeds field capture – 20073. Rook field capture – 20094. Grazing licence areas – 2010 (in development)• Public data setsDOC, Councils, and University• First version was created as a researchproject• No experience in business processes andplanning• Redeveloped to incorporate what was learntfrom other projects• New options available561

2005 20097STEMsCommon elements betweenprojects• ArcPad Studio• Embedded with VisualBasic Script• Assistance from theuser community• Fields and GPS data capture• Datum coordinates• Projection coordinates• Accuracy – position dilution of precision (PDOP), estimatedpositional error (EPE)• Date• User name910• UsabilityCommon elements betweenprojects• Dropdown boxes vs. free form text entry• Command buttons instead of “Page Tabs”• Only show essential pages• Recycling of existing scripts• Planning for the projectConclusions• Develop a document that outlines some of thebasic guidelines for application development• Freely available to the wider GIS communityand technology providers• Training provided by pre-service (university) orin-service (in-house or Eagle)• Next level of integration (ArcMobile) will extendfield-based applications11122
