- 1. cUSING ARCGIS ONLINE TO ASSIST IN MAPPING HAWAI‘I’S AGRICULTURAL FOOTPRINT Hawai‘i 2015 Statewide Agricultural Land Use Baseline UH Hilo Spatial Data Analysis and Visualization Lab (SDAV) for the State Department of Agriculture
- 2. INTRODUCTION ▪ The last statewide agricultural mapping implementation was published in 1980 ▪ Hawaii Department of Agriculture (HDOA) ▪ Office of State Planning (OSP) ▪ Deficiency in data ▪ spatial mapping of agricultural production ▪ collection of specific crop production ▪ This study builds upon an award-winning work conducted for the County of Hawai‘i Department of Research and Development by the UHH SDAV lab in 2012. Hawai'i County Food Self-Sufficiency Baseline 2012 ▪ Report authored by : Jeff Melrose MURP, Ryan Perroy Ph.D, and Sylvie Cares MA
- 3. CONTRACT OBJECTIVES ▪ Focused on commercial farming efforts across the state. ▪ 3.0 acre minimum mapping area for crops. ▪ Every effort is being made to locate and map smaller commercial agricultural. ▪ Creation of digital feature layer, cartographic maps & reporting. ▪ Creation of website !
- 7. WEB MAPPING APPLICATION ▪ HTML 5 & ESRI JavaScript API ▪ Excellent API Library already created ▪ Open source ▪ No need for end-user plugin ▪ Serviced using ArcGIS Online ▪ No GIS Server ▪ Uncertainty in user participation ▪ Enabled with web editing capabilities ▪ User could add point and attribute information directly to map
Editor's Notes
- The last statewide agricultural mapping implementation was published in 1980 Produced by creating hand crafted maps by the Hawaii Department of Agriculture (HDOA) and later digitized by the Office of State Planning (OSP) Since that time Hawai‘i has suffered a deficiency in data, not only in the spatial mapping of agricultural production, but also in the collection of specific crop types. Seeing a need to improve an update ag data Hawaii Department of Agriculture contracted the SDAV lab to continue upon the award winning work of the County of Hawai‘i Department of Research and Development
- mapping project is focused on commercial farming efforts that make a reasonable financial contribution to the farmer and produce products that are either sold for local consumption or exported elsewhere. Contracts call for a 3.0 acre minimum mapping area for crops. Every effort is being made to locate and map smaller commercial agricultural operations as well. Creation of digital feature layer, cartographic maps & reporting Layer was created with the intent of mapping Agricultural land use verses land cover,.. layer was digitized using up to date imagery, ground truthing, and information from the agricultural community. Via Discussions with landowners, farmers, agencies
- The website could be anything : data table, email information, or web mapping application ;
- Creation of website ! In order to receive input from the agricultural community, a web mapping application was developed using ESRI’s JavaScript API and serviced using ArcGIS Online. The web mapping application used the preliminary crop layer to display recorded agricultural farms that allowed the end users to search for their farm by address or location. End users were also able to add data and comment on any discrepancies to both confirm and improve the accuracy of the agricultural land footprint. The web mapping component was written using HTML 5 & ESRI JavaScript API Great Library already created application programming interface (API) no need to download plugin like Microsoft Silverlight or Adobe Flexviewer Serviced using AGO
