The steps required to migrate to geodatabase technology are different for each organization. This session will discuss how ArcMap extensions can ease this transition by enabling mapping professionals to continue using tools they are familiar with. Comprehensive ArcMap extensions give users tools to perform mapping functions such as parcel splits and merges, annotation, CAD file import and manip...

As part of an ongoing research project, geovisualisations of bushfires were delivered at GPS-determined locations to volunteer firefighters from the Country Fire Authority’s Macedon Ranges Group. The participants skill level ranged from basic wildfire firefighter trained through to captain of brigade. The location-based scenario training exercise is called CODE RED: MOBILE. Using information fr...

A yield estimation method by remote sensing was used to estimate the yield of winter wheat in Jiangsu province, China. The first step of this study was to extract the planting area of winter wheat from environmental satellite images and land -use map of Jiangsu province, meanwhile, correlation analyses were performed by using 8-day of composite Leaf Area Index (LAI) data from Moderate Resolutio...

The preliminary geologic map of the McTarnahan Hill quadrangle, first released in 1999 in PDF format, was originally drafted in Adobe Illustrator. This Second Edition (Revised 2009) was converted and modified slightly in ArcMap Version 9.3. The Quaternary unit descriptions were not significantly changed from the original map. Bedrock unit descriptions were modified and corrected, and sections w...

The number of satellites visible to a Global Navigation Satellite System (GNSS) receiver is important for high accuracy surveys. To aid with this, there are software packages capable of predicting GNSS visibility at any location of the globe at any time of day. These prediction packages operate by using regularly updated almanacs containing positional data for all navigation satellites; however...

Evapotranspiration (ET) is important to hydrologists as well as regional planners. Methods for the calculation of ET require land use as well as weather and solar energy inputs. In this paper we present an ArcMap toolbar for the calculation of spatially distributed ET from ground based weather data. The toolbar provides functionality to interpolate weather data over the region of interest and c...

Flow maps are used in order to indicate movements by persons or objects in a given time period. The major problem concerning the production of flow maps is the appropriate placement of movement lines in the map. This paper presents a method of placing lines automatically, based on a modification of an exisiting algorithm. The algorithm has been implemented as an ArcMap extension and was subsequ...

Columnar display of linear referenced data portrays dozens of attributes of linear features simultaneously, visually, and interactively. In this genome-like display, each attribute is a layer of an ArcMap data frame. Location is in traditional geographic space and as distance along a measured route created with ArcINFO dynamic segmentation. The resulting display is familiar to investigators acc...

Layers in ArcScene containing polygon features can be extruded to create 3D blocks for display in the current scene. While this is useful for representing flat-roofed buildings within ArcScene it does not create a new, 3D shapefile and cannot create buildings with peaked or curved roofs. A method to create 3D shapefiles representing buildings with complex roofs and then export these objects to ...

The Soil Survey Geographic (SSURGO) database provides the highest resolution for a county-wide soil database in the United States. AvSWAT and ArcSWAT are developed for using soil input prepared in a format of the State Soil and Geographic (STATSGO) database. The available SSURGO processing extension tool currently works only with AvSWAT but not with ArcSWAT. The purpose of this study is to deve...
