Accuracy
1st Generation* | 2nd Generation | Notes | |
---|---|---|---|
Ground Sampling Distance (GSD) | - | 3" or 7.6 cm | GSD for obliques vary depending on the vertical GSD and the image angle (35-50 degrees equivalent to GSD variation of 6.8-8.7 cm). |
Absolute Horizontal Accuracy | - | n/a | |
Vertical Measurement Accuracy | - | 6" or 15 cm | |
Datum / Projection | - | n/a | |
Image Bands | - | RGB Natural Color |

FAQs
Oblique content is available as individual photos, each taken from a different cardinal direction, ordinal direction, or occasionally both. Whether you see cardinal (North, South, East or West) or ordinal (North-East, South-West, South-East, North-West) photos depends on the orientation the survey flight took. The most difficult part of measuring using either method is accurately picking the top and bottom of the object due to shadows, obstructed views and the limits of resolution. With practice behaviour becomes more consistent, and in tests of measuring with both 3D and oblique images, results are consistently within about 1 meter of each other. No, viewing True Ortho imagery does not count towards your standard imagery data allowance. True Ortho is currently included with 3D Viewer and 3D Export subscriptions. Theoretically, the oblique images offer higher accuracy, but in practice, actual measured accuracy will be determined by how well the endpoints of the measurement can be seen and how well the tool is used to place the start and endpoints. This can be affected by zoom level, perspective, and any obstructions. You can use the Snapshot tool to export an image of:
