GIS consulting

Dirigo Aerial & GIS provides custom GIS mapping and geographic data support for projects in Maine. Our portfolio includes municipal map catalogs, digitized tax maps, and wetland mapping. We organize the work around your project goals and intended use, with the map layers, analysis, and final deliverables agreed upon before work begins.

GIS consulting costs vary with the project scope, source-data quality, required analysis, and final maps or files. Preparing one map from usable data involves different work than digitizing older maps or combining several datasets. Send your project location, available files, requested outputs, and deadline for a project-specific quote.

Yes. We can review your existing maps and GIS data to determine which information is suitable and what may be missing. Useful details include the file formats, data sources, collection dates, and any known coordinate systems or accuracy requirements. If you do not have prepared GIS files, start with the location and the problem you need to solve.

Yes. Our portfolio includes digitized tax maps and municipal GIS map catalogs for towns in Penobscot County, Maine. We discuss the source maps, required layers, and how staff or the public will use the finished products. Digitizing organizes existing mapping information; the resulting map remains dependent on the quality and limitations of its source data.

Depending on your project, deliverables may include finished PDF maps, geographic datasets, or both. The formats are agreed upon before work begins, based on whether you need to view, print, edit, or analyze the results. Tell us which software your team uses so we can confirm compatibility and any viewing or editing requirements.

GIS project timelines depend on the scope, source-data readiness, analysis, and review requirements. A single map prepared from organized data may involve fewer steps than a map-digitizing or multi-dataset project. Include your deadline when requesting a quote so we can discuss availability and agree on a realistic schedule rather than promise a standard turnaround.

Yes, where the datasets are suitable for the task. Aerial imagery can provide current visual context, while LiDAR-derived layers can add terrain or height information to existing GIS maps. Coordinate systems, vertical references, collection dates, and data quality must be considered before combining them. We confirm the appropriate layers and outputs during project scoping.

Send the project location or area of interest, your mapping or analysis goal, and a description of the data you already have. Include the intended audience, preferred maps or files, relevant software, and deadline. If you are unsure which deliverables you need, explain the decision you are trying to make so we can discuss a suitable scope.
