Mapping services offered on this website are based on public GIS
Landowner mapping services
Have you ever wanted to go beyond looking at your property on Google Maps or Google Earth? I provide GIS mapping services and products for farmers, ranchers, owners of woodlots and acreages, incorporating aerial photos, lot boundaries, elevation data, soil maps, and customer information for property plans, design, and management of small farms or acreages. The derived maps are geocorrected and provide an aerial view of the land including elevation, slope and aspect. The maps can be used to obtain measurements and perform site planning for buildings, fencing, crops, landscapes, greenhouses, and gardens. A detailed map of the lay of your land provides you with information about potential wet and dry areas or best sun exposure, and helps you plan and manage your acreage in an environmentally sound manner. I provide different levels of services and packaged products. The products include free mapping software and instructions for use. No job is too small. I invite you to look at some examples of my work.

All map packages include a CD with data layers and a free viewer to display the data in 2D and 3D, turn layers on and query values contained in the data layers (elevation, slope, soil type, etc.). Detailed instructions for use are included.
What you will get
1. Instructions for use
Detailed instructions on the installation of the free viewer, viewing the data, and content of GIS layers
2. GIS Viewer
The viewer is ArcGIS Explorer, a free GIS viewer from ESRI®. ArcGIS Explorer is intuitive to use for exploring and visualizing spatial data. The viewer is included on the CD, or it can be downloaded from http://www.esri.com/software/arcgis/explorer-desktop . Similar to Google Earth, the viewer’s base map layer displays high resolution aerial imagery, over which the GIS layers are shown. Various other base maps can be added from the ESRI® online baseman gallery, including street maps and topography data. You can draw over the existing data layers to add your own information, and basic spatial analysis functions are available.

3. Map file
The map file is an ArcGIS Explorer format file (*.nmf). When opened in the software, the entire project with folders and data layers is displayed. A user not familiar with GIS can simply open the file and immediately explore the data. The map file contains the Data Layerpack and individual data layers that are provided on the CD (See examples here).
4. Data Layerpack
The data layerpack is a single file that includes raster and vector layers with their associated map legends. A layerpack has the advantage that the data will display with the legend that the map creator designed. This allows the user to simply turn the data on and visualize it with an appropriate legend. Vector layers (soils and contour files) can be queried by clicking on the layer which returns a popup window that displays the value at that location.
5. Individual data layers
In these individual data layers, the user can click on the raster layer and a popup window will display the value at that location. For vector layers (contours), the user can also change the appearance (color, size) of the lines. The underlying data layers are identical to the ones in the layerpack, but the display is in grey scale.

Premium landowner map package
This package contains all the data layers of the expanded landowner map package plus these additional products:
About the data
The data layers you will receive are assembled from county, state, and federal GIS data depositories. The soils data are from the NRCS Web soil survey. For the most part, the data are free, which keeps the cost down for the landowner package. As a result, data availability and resolution will vary based on your location. Contour lines may vary in resolution from 2 ft to 20 ft, and DEMs may vary from 1m to 10m. Slope, aspect, hillshade, and solar radiation maps are derived from the DEM and will have the same resolution as the DEM.
The informational details you can obtain from the data depend both on the data resolution and the size of your property. A minimum property size for obtaining sufficient detail with a 2ft contour interval is around 2 acres, but properties of 5 acres and larger are more suitable. Likewise, for larger properties, coarser resolution DEMs and 10-20ft contour intervals are appropriate. When you order a small landowner package, data availability and resolution for your location will be evaluated and we will inform you if there is a lack of data or insufficient resolution for your property’s size.
We are based in Oregon, and have a good selection of data for that state, but data can be provided for any state. We also provide map packages for other countries if data are available. For the entire state of Oregon, 4-band aerial imagery at 0.5 m resolution is available, and imagery at 15 to 30 cm resolution is often available in selected areas. High resolution DEMs at 1 m resolution are becoming increasingly available for many locations, although 10 m resolution is more commonly for most areas.
How to Order
Before we request payment, we will verify which data and resolution is available for your property and send you an email describing the map package that can be created for you. If there is a lack of data or insufficient resolution for your property’s size, we will tell you. Please fill out the Request for Mapping Work form with your contact details, and we will get back to you promptly.
