Welcome to NACIS 2014 in Pittsburgh! This is the annual meeting of the North American Cartographic Information Society (NACIS). The theme for this year’s meeting is Cartography and Time. See the schedule below and go to the NACIS website for more details.

[If you are a presenter and want to provide a link to your slides in your presentation description below, send an email to veep@nacis.org.]

The North American Cartographic Information Society, founded in 1980, is an organization comprised of specialists from private, academic, and government organizations whose common interest lies in facilitating communication in the map information community.

Managing Water Resources with Time Enabled Image Services
Caitlin Scopel, ESRI
Daniel Siegel, ESRI
Climate change is affecting the way we manage our water resources, especially in the western United States, where many states have been suffering from drought. To help policy makers at all levels of government make vital decisions about water resources allocations, we have created analysis-ready image services that show how hydrologic conditions change over time. Precipitation, evapotranspiration, soil moisture, and runoff are all necessary pieces of the water budget, and when time-enabled, allow for historical and future views into water resources management. How does drought affect soil moisture over time? How does precipitation affect runoff over time? These are important questions that policy makers will need to answer in order to provide a stable future for the citizens of planet earth.

Spatial-Temporal Displays of Daily Climate Data
Christopher League, Long Island University-Brooklyn
Pat Kennelly, Long Island University-CW Post
Maps of climate change abound, but often display a small amount of data for each discrete location. Other graphs or displays show voluminous climate data for a particular location, but are often not specifically developed for geographic display. We have designed a three-dimensional cartographic display method for daily temperature data at particular locations that drapes a surface over a helix of variable radius. The length of the radius varies with temperature, and each turn of the helix represents one year. Using techniques common to terrain representation, we apply hue and saturation to the surface based on temperature, and value based on relief shading. Multiple helical surfaces can be displayed in one geographic scene, and the viewing direction corresponds with views of the same seasons for all helical displays. We see this method as effective in displaying high-resolution temporal data within a geographic framework.

Change Detection Research for the US Topo
Kristin Fishburn, USGS
Andrew Stauffer, USGS
The National Geospatial Technical Operations Center of the U. S. Geological Survey is currently researching an automated or semi-automated vector change detection process to support streamlined maintenance of data, products, and services in The National Map (TNM) (http://nationalmap.gov/). The use of change detection tools to identify change in five of the eight TNM data themes (Hydrography, Transportation, Boundaries, Structures and Geographic Names) has great potential for streamlining maintenance resource expenditures for the US Topo, the USGS 1:24,000-scale digital topographic map series. This presentation will focus on the US Topo product, providing a general overview of these maps and their production schedule. Our change detection research will be discussed briefly, to include methodological workflows and data storage strategies to help identify database changes. We will conclude by discussing how the results of vector change detection could directly impact US Topo map production and maintenance.

Modeling and mapping sand dunes encroachment risk using satellite data in the United Arab Emirates
Abdelgadir Abuelgasim, United Arab Emirates University
Naeema Alhosani, United Arab Emirates University
Sand dunes encroachment into urban areas and transportation networks is a frequently occurring phenomenon in the United Arab Emirates (UAE). The UAE is located in one the world's largest arid region with strong prevalence of sand dunes movement and encroachment into urban areas, particularly in the last few years. The primary purpose of this study is to develop a land surface process model that models the sand dunes movements and further generate an index hazard map of potential encroachment risk areas in the UAE.  For this task we use land cover maps generated from Landsat TM and Landsat OLI data coupled with meteorological information of wind direction, wind speed and precipitation. Using the developed sand dunes movement model a sand dunes encroachment risk map is generated to help decision makers in making informer decision that mitigate the effects of sand dunes encroachments in the UAE.
