  • Applied Information Management Services

  • GIS and Database Application Development Services

    GIS and Database Application Development Services

    The data analysis techniques that GIS can provide are more powerful and cost effective when users can apply them repeatedly for varying situations. We make this possible by writing customized GIS tools and applications for our clients. We start by fully understanding the user's needs and defining the workflow. Next, we develop and test the spatial analysis technique that will form the basis of the application. Once the client approves the technique,...

  • Data Discovery, Documentation, and Access Services

    Data Discovery, Documentation, and Access Services

    Stone experience with Data Discovery, Documentation and Access technology can smooth the clients path into a least costly data management solutions. The advent of Internet data portal technologies allows one organization be engaged in a distributed network of data providers without being an active data harvester and disseminator of data. New technologies allow data to be searched from anywhere and using WMS or WFS services from other data providers...

  • Spatial Analysis Services

    Spatial Analysis Services

    Whether the challenge is identifying watersheds vulnerable to pesticide exposure or determining the onsite wastewater treatment capacity of a new neighborhood development, or understanding the volume of food scraps available to supply composting sites or where can proposed wind towers be seen from, spatial analysis using GIS enables the integration of complex data sets to support environmental decision making.

  • Information for Sustainable Development (ISD) Services

  • Baseline Data Collection and Multi-Sector Country Profiles Services

    Baseline Data Collection and Multi-Sector Country Profiles Services

    To monitor project and program effectiveness, it is essential to develop a baseline of information to see if progress is being made. Stone uses baseline data to profile current conditions, and compares all new data to the baseline to measure change. We have developed methods that portray existing information in a ready-to-use format for identifying current status. Our design anticipates the capture of new program data or ongoing data collection...

  • Needs Analysis and Implementation Solutions Services

    Needs Analysis and Implementation Solutions Services

    Where does GIS make sense? A needs analysis is the first step in implementing a Geographic Information System (GIS) in any organization. It is a systematic look at how user groups function and what skills, spatial data, and software tools they need to succeed in their work. At the conclusion of a needs analysis, we provide the organization with the technical and implementation plans necessary to develop a Geographic Information System. In addition to...

  • Poverty Mapping and Vulnerability Assessment Services

    Poverty Mapping and Vulnerability Assessment Services

    Developing a baseline for understanding what areas are poorest and how to measure progress is an important first step in improving the standard of living of vulnerable populations. The process we use is simple. First we identify and map all the relevant indicators of poverty that are available in a country’s databases. Then we compile and integrate the data sets in a spatial information system. Finally, we analyze the data and create an...

  • GIS Database Design, Development, and Management Services

    GIS Database Design, Development, and Management Services

    Geographic Information System (GIS) technology is only as good as the data behind it. Our expert database design minimizes the potential for data problems as the demand for GIS use grows in your organization. Our efficient techniques and experienced quality-control standards create high-quality databases that last. We use a variety of tools, including scanning, raster-to-vector, sub-meter horizontal accuracy GPS with data logger, and expert manual...

  • Agrochemical Fate and Exposure Services

  • Surface Water Monitoring Services

    Surface Water Monitoring Services

    Between the edge of a farm field and a downstream water treatment plant is a network of drainage ditches and streams. We monitor the water and biota in these perennial streams to assess the potential impact of pesticides on aquatic animals and plants. We conduct stream sampling at this intermediate scale, where environmental concentrations of a pesticide need to be measured for comparison with ecotoxicological levels of concern.

  • Environmental Fate Modeling Services

    Environmental Fate Modeling Services

    Since 1992, Stone has been assisting agrochemical clients with the registration of new chemicals, and the maintenance and mitigation of existing registrations. As a critical part of every registration project, our modeling team is one of the most experienced in the industry in predicting the environmental concentrations of an agrochemical in surface water and groundwater.

  • Edge-of-Field Runoff Studies Services

    Edge-of-Field Runoff Studies Services

    Stone has conducted nine studies quantifying runoff losses of crop protection and lawn care chemicals following rainstorms and irrigation. The objective of these studies was to assess the runoff potential of pesticide products under actual use conditions. In our most recent study, we qualified and instrumented 20 sites throughout the Midwest, trained contractors and growers to collect samples, and managed all sampling activities for the duration of...

  • Community Drinking Water Monitoring Services

    Community Drinking Water Monitoring Services

    With 13 drinking water monitoring studies successfully implemented and 11 completed, we have led the industry in conducting such studies since 1994. These studies have involved several hundred community water systems (CWSs) across the US. We have worked with the Acetochlor Registration Partnership on the largest such study yet conducted, which involved almost 200 CWSs and spanned a period of seven years. Our smallest study involved just five systems...
