Why Innoter
Prompt access to archives
Suitable archive imagery can be obtained faster when the required area and date are already available from operators.
No aviation clearances
A new satellite survey does not require the flight clearances typical of aerial surveys.
Large and remote areas
A single satellite pass covers large areas and makes it possible to work in hard-to-reach regions.
Direct agreements with operators
Distribution agreements help select archive imagery and order new surveys from different providers.
Software and server infrastructure
Modern software and computing capacity for quality control and processing of large data volumes.
Experienced specialist team
Years of experience on complex projects and specialists in cartography, photogrammetry and remote sensing.
DTM scales, survey and source-data requirements
The composition depends on scale, archive or new survey, GCPs, projection and object-composition requirements.
1
A digital topographic map (DTM) is a digital model of the terrain recorded on a machine-readable medium in an established structure and codes, in the projection, sheet layout, coordinate system and heights adopted for the map, with accuracy and content corresponding to a topographic map of a given scale.
DTMs are created at scales 1:10 000, 1:25 000, 1:50 000, 1:100 000, 1:200 000, 1:500 000, 1:1 000 000 and formed as arrays of digital cartographic information for areas bounded by the sheet frames of the corresponding topographic maps of the same scale.
The main objective of creation or update is a product that matches the actual state of the terrain as closely as possible, in accordance with regulatory and technical documents and the terms of reference.
2
DTMs at scales 1:10 000 and 1:25 000: detailed study of the terrain; precise measurements and calculations for construction of engineering structures; crossing water barriers and other purposes.
DTMs at scales 1:50 000, 1:100 000 and 1:200 000: study and assessment of the terrain; measurements and calculations for design and construction of military engineering structures and facilities; preparation, command and determination of coordinates of starting positions in military units.
DTMs at scales 1:500 000 and 1:1 000 000: study and assessment of the general character of the terrain for operational planning and conduct; use in aviation as aeronautical charts.

For high-quality preparation, area coordinates, map parameters and, if available, GCPs are required. Permissible ground resolution (spatial resolution of images), m:
- scale 1:2000 — 0.1
- scale 1:5000 — 0.25
- scale 1:10 000 — 0.5
- scale 1:25 000 — 1.25
- scale 1:50 000 — 2.5
Satellite imagery for 1:5000 maps: GNSS photo-control points, a DEM, 1:5000 orthophotomaps, field interpretation, a base with a 1 m contour interval. From aerial photography for 1:5000 — including orthophotomaps with resolution down to 0.10 m. A 1:25 000 base — from satellite imagery with ground resolution of not worse than 1 metre.

Archive data are already available to the operator. Ordering a new survey does not require the clearances from competent authorities typical of flights. Satellite imagery does not require a site visit, unlike aerial photography and UAV surveys.
Satellite images are also used to compile overview topographic maps, skipping the multi-stage transition from large scales to medium and small scales. There is experience creating general geographic maps, for example a national base map at a scale of 1:250 000 from photomaps based on satellite images at a scale of 1:1 000 000.
Repeat aerospace surveys are convenient for regular update. Mapping of the country’s territory at a scale of 1:100 000 was completed in the mid-1950s, at 1:25 000 — by the 1980s. Satellite photographs make it possible to start updating the scale series in any order and to update maps of the entire series at once.

For topographic maps (plans) showing existing and designed field facilities at a scale of 1:10 000–1:25 000 the following are used:
- materials of the state cartographic and geodetic fund of the Russian Federation;
- data from as-built and control geodetic surveys of utilities and structures;
- design materials for field-facility objects;
- satellite imagery acquired with electro-optical sensors in the visible and IR spectral bands at very high resolution (0.3–1.0 m).
The basis also includes mine-surveying requirements in field development. When creating and updating a base of any scale, object composition is reduced to a publicly releasable state. Work is performed in accordance with the classified-information regime in the Russian Federation.
