Discover our core GIS services, designed to support critical sectors and enhance decision-making.
1. GIS Mapping & Cartographic Design
GIS Mapping & Cartographic Design involves the creation of visually appealing and highly accurate maps that convey geographic information. Our experts utilize advanced mapping software and techniques to represent spatial data effectively.
- Thematic Mapping: Producing specialized maps to showcase specific themes such as land use, zoning regulations, utility infrastructure, and population demographics.
- Custom Basemap Creation: Creating detailed base maps tailored to specific project requirements, providing context for overlaying additional spatial data.
- Professional Map Layouts: Designing maps optimized for clarity and readability in reports, proposals, presentations, and digital platforms.
- High-resolution Export: Providing maps in multiple versatile formats, including PDF, Geodatabases (GDB), Shapefiles (SHP), and CAD formats (DWG, DXF).
2. Spatial Data Processing & Analysis
Spatial Data Processing & Analysis transforms raw geographic data into valuable insights using sophisticated analytical methods and GIS tools.
- Spatial Analysis Techniques: Employing methods like buffering (creating distance-based zones), overlays (combining multiple data layers), proximity analysis (measuring distances between features), and network analysis (assessing connectivity and routes).
- Suitability Modeling and Hotspot Identification: Analyzing data to determine optimal locations for various uses, and identifying geographic areas with high concentrations of specific attributes or events.
- Terrain and Elevation Analysis: Examining elevation data to determine terrain features like slope, aspect, elevation contours, and watershed boundaries.
- Demographic and Statistical Correlation: Identifying relationships between geographic features and demographic or statistical information to support decision-making processes.
3. Digitizing & Vectorization
Digitizing and vectorization convert physical maps, scanned images, or CAD drawings into structured, GIS-compatible digital formats.
- Manual and Automated Digitizing: Tracing geographic features manually or using automated software to convert paper maps into digital formats.
- Vectorization: Converting raster (image-based) data into vector formats, making data more versatile and easier to manipulate.
- Quality Assurance/Quality Control (QA/QC): Thoroughly reviewing digitized data to ensure accuracy and attaching detailed attribute data.
- Detailed Feature Tracing: Precisely mapping and digitizing specific geographic features like property parcels, utility lines, and infrastructure components.
4. CAD to GIS Conversion
CAD to GIS Conversion services transform engineering and architectural designs from CAD formats into functional GIS datasets.
- Cleanup and Structuring: Refining AutoCAD drawings (DWG/DXF) to ensure they are organized and ready for GIS integration.
- Conversion of Layers and Blocks: Transforming CAD layers and blocks into GIS features with attributes that allow for spatial analysis.
- Coordinate System Assignment and Transformation: Assigning appropriate geographic coordinate systems to CAD drawings to ensure accurate alignment with real-world locations.
- Integration: Combining converted CAD data seamlessly into existing GIS databases or shapefiles.
5. Topology Cleaning & Data Validation
Topology Cleaning & Data Validation ensures that your GIS data is accurate, reliable, and free of geometric errors.
- Detection and Correction: Identifying and fixing common errors such as slivers (tiny unwanted polygons), gaps between polygons, and overlaps of adjacent features.
- Enforcement of Topological Rules: Applying rules to ensure data integrity, such as preventing dangling lines or overshoot errors.
- Geometry Validation and Snapping: Correcting geometric inaccuracies by snapping vertices and edges to ensure spatial precision.
- Attribute Consistency Checks: Verifying and standardizing attribute data to ensure accuracy and uniformity.
6. Geodatabase Design & Management
Our GIS services include advanced geodatabase design and management to help clients create, structure, and maintain spatial databases for optimal organization and performance.
- Creation and Management: Setting up new geodatabases tailored to client needs and managing ongoing data storage and retrieval.
- Configuration of Feature Classes and Domains: Defining specific geographic features and setting attribute standards to ensure consistency.
- Advanced Schema Design and Database Versioning: Creating database structures and managing multiple data versions for collaborative environments.
- Metadata Documentation and Indexing: Documenting dataset details and indexing attributes to improve searchability and data management.
7. Georeferencing & Coordinate System Services
Georeferencing accurately positions spatial datasets on the Earth’s surface using standardized coordinate systems.
- Raster Image Georeferencing: Aligning scanned maps with real-world coordinates for accurate spatial representation.
- Coordinate System Assignments and Transformations: Setting and converting geographic datasets between coordinate systems such as WGS84 and Universal Transverse Mercator (UTM).
- Projection Audits: Reviewing large-scale datasets to ensure correct projections and coordinate alignment.
- GPS Data Integration: Incorporating GPS-collected data into existing GIS layers to enhance spatial accuracy.
8. Custom Python (ArcPy) Scripting & Automation
Custom Python (ArcPy) scripting automates repetitive GIS tasks, improving efficiency and accuracy in spatial data processing.
- Automated Batch Processing: Developing scripts for executing large-scale repetitive tasks without manual intervention.
- Efficient Data Manipulation: Automating tasks such as attribute updates, spatial joins, and extraction of specific geographic information.
- Large Dataset Handling: Optimizing processing and management of large spatial datasets through advanced scripting techniques.
- In-Memory Processing: Utilizing efficient scripting approaches to process data directly in system memory, thereby enhancing performance significantly.
9. Remote GIS Support & Consulting
Remote GIS Support & Consulting provides flexible, expert GIS services tailored to client needs, eliminating the need for in-house infrastructure. We align our support with established GIS principles, including those outlined by Esri, to ensure consistency and quality in every engagement.
- Flexible and Rapid Turnaround: Providing timely GIS support and project execution according to client schedules.
