IPEN GIS Templates 2.0 Marc Adams Arizona State University May 19-20 San Diego 2014 IPEN San Diego 2014
Why GIS Templates? Need for greater specificity to common concepts, clearer definitions, and guidance on common GIS variables and procedures for IPEN Adolescent. Following these templates closely will ensure that the IPEN Adolescent study has a common set of comparable GIS variables Provide transparency. Document consistency and any deviations. Critical for GIS comparability evaluation IPEN San Diego 2014
IPEN Adult: Walkability - 15 Cities on 5 Continents � IPEN San Diego 2014
What’s New? Version 2.0 of templates released! www.bit.ly/IPEN_template_drafts Open for public comments. Please send by June 10 th ! We want to know your thoughts, concerns, confusions, gaps All existing templates revised for IPEN-A! Incorporated lessons learned from IPEN Adult Resolved inconsistencies across templates Standardized units of measurement (metric) Handling missing values Now clearer and w/improved guidance on GIS procedures More organized, easier to to read and use! IPEN San Diego 2014
What’s New? (cont.) 4 New Templates Templates released this week Template questions answered online now Qualtrics Online Survey System Will make preliminary reviews and comparability evaluation quicker IPEN San Diego 2014
Nomenclature for Variables Required variable means that this variable has been judged to be most likely completed across all countries. All countries should produce the required variables, if you have data available to calculate it. Desired variable means that this variable has been judged to be of greater importance or higher quality than the required ones. Desired variables should be calculated in addition to the required variables. Speculative variable means that it is unknown whether this variable can be completed by even a subset of countries. Speculative variables should be calculated, by those who can, but are considered exploratory. IPEN San Diego 2014
Existing Templates: Variable Updates Removed some rare and redundant variables E.g. crow-fly access to parks School buffers added. Sizes and types to be determined soon. Operationalized different types of bus and rail networks into a reasonable hierarchy IPEN San Diego 2014
Nomenclature for GIS Procedures Recommended procedures should be used instead of acceptable procedures. Recommended procedures have been judged to be more common or precise methods of calculating the variables. All countries should attempt to perform recommended procedures. Acceptable procedures should be used only if recommended procedures cannot be used , or if recommended procedures have been deemed inappropriate for country-specific reasons. Acceptable procedures are less accurate than desired procedures, but acceptable to use. Speculative procedures are the least accurate or least common procedural option. Should only be used if recommended or acceptable procedures cannot be accomplished IPEN San Diego 2014
Updated Guidance on GIS Procedures Opportunity to improve comparability of various GIS methods across countries Existing templates now have clearer examples for classifying land use subcategories (Appendix A) Recommended and acceptable procedures for: Multiple parcels that intersect and partially overlap participants buffer edges Parcels with vertical mix use Parcels with horizontal mixed use IPEN San Diego 2014
New GIS Templates Neighborhood Selection (released Nov ‘ 13) 1. Office Land Use 1. 2. Vacant Land Use Regional Accessibility 3. Invite your comments on these IPEN San Diego 2014
IPEN-A Qualtrics System Improved infrastructure for answering template questions Easier, more standardized reporting. Quicker prelim checks Verifications, skip patterns, and conditional logic in background You will receive a copy of responses via email and know we received them immediately CC can export answers to Excel, SPSS, etc. IPEN San Diego 2014
Final Steps Interest in other templates? Industrial land use? Need consensus on required and desired buffer sizes and types before we can finalize buffer template! 250m, 500m, 1km, 2km, 2.5km Detail street network buffers, sausage buffers, pedestrian enhanced buffers Residential AND school buffers planned (30 possible buffers) Home-to-school route buffers suggested IPEN San Diego 2014
Next Steps (cont.) Share draft templates with GIS staff and investigators.

MAPS -Global Goal: Using MAPS Abbreviated as a starting point, modify and add items for use in an international context. The instrument will be used on participant- level routes, beginning from a participant’s home and traveling ~. 25 miles (~400m) in the direction of a pre-determined destination. The tool will be completed either on site or remotely using Google Streetview. Instruments compiled: Bikeability Toolkit (Australia) Route-based checklist. Each item rated in three domains (commuting/utility, recreation, primary school student) as either satisfactory, issues, or N/A. If there are issues, raters are provided a box to answer where/what the problem is. Additional section regarding off-road paths not included. ALPHA (Europe) Includes sections: Types of residences, distance to local facilities, walking and cycling infrastructure, maintenance of walking and cycling infrastructure, safety, how pleasant for walking or cycling, walking and cycling network EAST_HK, Environment in Asia Scan Tool (Hong Kong) Developed from SPACES, Analytic and Checklist Audit Tool (Brownson), Irvine-Minnesota Inventory (Boarnet) and Chinese NEWS. Data collected on undefined 'street segments', likely US routes (could include intersections). REAT, Residential Environment Assessment Tool (UK) Completed on postcodes (containing on average 17 households, often defined as a single street of houses). Items assessed either by property or by postcode. FASTVIEW, Forty Area Study Street View tool (UK) Google Streetview tool, developed from PERS (Pedestrian Environment Review System). Completed on 'audit links' of 50-300 meters, mostly 'stretched between road junctions' SPACES, Systematic Pedestrian and Cycling Environmental Scan (Australia) Data collected on either both sides of street segments (between two intersections), one side, or for multiple segments (indicated below). When applicable, intersection items are completed for the intersection at the beginning of the segment. SPEEDY/ISCOLE School audit tool. Mostly in-school, but some questions regarding surrounding area (included here). IPEN San Diego 2014
