Vesta

Visualization and Exploratory Space-Time data Analysis

 

Vesta is a powerful tool to visualize temporal and spatial trends in a variety of formats. Vesta is a reworking of our software, SpaceStat. We have implemented a fresh, user-friendly design that makes for smooth data importing and visualizations, evaluating spatial patterns, and making spatial predictions and time forecasting.

We have designed and built on the foundation that BioMedware created for geospatial data analysis in a way that is accessible for non-expert users with detailed support material, as well as for the seasoned geostatistician.

Vesta Features

Vesta 1.0 features data visualization and exploratory analysis:

  • Support data sources with different geographic projections such as esri Shapefiles, and Excel files
  • The maps created in Vesta overlay data over map tiles background, similar to viewing a route on a virtual map
  • Conduct exploratory analysis through the visualization of data in table, map, histogram, scatterplot, heatmap, timeplot, and boxplot 
  • Highlight the same observations on multiple graphs (i.e., maps, histograms, scatterplots) by linking and brushing 
  • Visualize time-dependent behavior of graphs and summary statistics simply moving a time slider bar
  • Export visualizations and tables as image files, and save project files

Future Features

Several analytical functionalities will be added incrementally in future releases of Vesta, including:

  • Joinpoint regression to model temporal trends and estimate the timing of any significant changes (look for Vesta 2.0!)
  • More comprehensive features for changing spatial support to derive the values of different attributes over different geographical units
  • Geostatistical methods to characterize spatial patterns and make predictions at un-sampled locations and unmonitored times using multiple data layers 
  • Regression models to estimate values of a given variable from a set of explanatory variables

How to use Vesta

Vesta allows users to make statistical inferences about data patterns that can inform policy and health decisions.

Infrastructure industry professionals often have a need to identify service lines that might be responsible for lead in water. Using Vesta, individual addresses and/or service lines are assigned a probability of lead contribution and a model is generated to help make informed decisions on what areas to further assess.

Cancer registries frequently explore ways to better communicate trends in cancer rates. Researchers can model cancer rates over time and space using our software. Being able to account for geographic variances in temporal trends can greatly improve health directives and policies.

Urban planning engineers explore ways to improve our living environment, including reducing the effects of environmental overheating. Professionals can track temperature trends and strategically “cool” a local environment by knowing where to have parks/forest areas as these generally keep the environment cooler.

How can farmers and agricultural enterprises optimize a plan for fertilizing crops? By mapping soil properties and crop yields, stakeholders can track how these factors change over time and make decisions for future fertilization schedules and/or watering schedules.

Air and land pollution is an ever-growing concern. How can a health environment exposome be quantified and interpreted? A person’s health is affected and influenced by the
totality of their exposures over their lifetime. Local data (air pollutants, water contaminants, industrial facility proximity, access to health facilities, etc.) can be used to create an “exposome” map and thus inform stakeholders about the range of factors influencing human life outcomes and make exposure assessments.

Get Vesta

At this time, we offer a Vesta 1.0 single seat license option at no cost for a limited time! A single seat license can be used by one user and installed on up to three workstations. The license will be valid through December 2023, and will be available for download until Vesta 2.0 is launched. Once Vesta 2.0 releases, we will no longer offer Vesta 1.0.

 

 

Installing Vesta

Once you acquire a Vesta license, check your email for the license key to install the software. For more detailed directions, click here.

Vesta requires Windows OS 10 and up. Vesta software requires internet connection to regularly validate license status and to load all map features. The software functions without internet connection as any other desktop app, however to have the full feature experience internet connection is recommended.
