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.
Scales, source data and work stages
The composition depends on the plan scale, archive or new survey, ground control points and the terms of reference.
1
A topographic site plan is a large-scale drawing of a plot of the Earth's surface in conventional symbols without accounting for the curvature of the geoid. The scale is constant in all directions.
The document is compiled from a topographic survey: the plan shows situation, terrain relief and objects with technical and metric characteristics.
Plans are produced at large scales from 1:5000 to 1:500 (the largest demanded scale: 1 cm of the plan is 5 metres on the ground) and do not account for Earth's-surface distortion. Maps are issued at smaller scales, cover larger territories and account for the curvature of the globe.
2
Permissible ground sample distance (spatial resolution of images), m:
- scale 1:500 — 0.1 m;
- scale 1:1000 — 0.25 m;
- scale 1:2000 — 0.5 m;
- scale 1:5000 — 1.25 m;
- scale 1:10 000 — 2.5 m.
For construction, 1:500 or 1:1000 plans are used in most cases. The most accurate are tree-by-tree plans and landscape surveys at 1:100 and 1:200.
3
Very-high- and high-resolution satellite imagery can be obtained faster: it may already be in the operator archives, and a new survey does not require approvals from competent authorities. Satellite imagery does not require a field visit, unlike aerial photography and UAV survey.
Aerial photography provides images with high spatial resolution (down to 1 cm/pixel) and a higher level of detail of orthophotomaps and models, a root-mean-square error (RMSE) of point coordinates of less than 10 cm, and can be performed under continuous cloud cover.
4
The main material is archive remote sensing data from spacecraft operators for the most current date, or a new survey. In addition, geographic descriptions, maps and atlases of a larger (smaller) scale, directories and customer data are used.
For an update, map products from the CGK&PD funds or products provided by the customer may be used.
5
Issue alignment, analysis of remote sensing data, source map materials, additional and reference materials: from 1 to 5 working days. Contract signing: from 1 to 5 working days. Receipt of images: from 3 to 10 days from the date of the 100% advance for remote sensing materials. Request and receipt of source map material from funds (if needed): from 1 to 20 working days. Digital orthophotomap creation: from 5 working days. Interpretation and vectorisation: from 15 working days. Adjacent-sheet joining and QC: from 5 to 10 working days. Report compilation: from 5 to 10 days. Total timeline: from 20 days.
Timelines depend on the number of nomenclature sheets, scale and type of product, availability of archive (existing) materials, additional and reference materials. Orthophotomap creation for interpretation and vectorisation — from 5 working days from the date of the 100% remote sensing advance; start of interpretation and vectorisation — from 3 days after orthophotomap start.

Saving on preparatory work is not always advisable. It is the basis for the preparation of other construction documents, and redrafting may entail significant costs. The cost of preparing a topographic plan varies depending on the detail and scale.
Topoplan is a schematic representation of the investigated land plot (terrain), on which the entire situation is displayed in conventional signs. They are created in a horizontal plane, where the parameters of objects are represented in a certain scale. In fact, a topographic plan is a projection of the terrain in a reduced form with height marks and binding to the coordinate system.
Inscriptions are made by certain cartographic fonts, taking into account the rules of location on the right of the scheme.
Map and plan in topography are identical concepts. The difference is that a map is provided on a smaller scale and covers larger areas, taking into account the curvature of the surface of the globe. Plans do not take into account the distortion of the land and are carried out in large scales from 1:5000 to 1:500, ie the largest demanded scale in 1 cm. plan 5 meters of land.
Topographic site plan significantly accelerates engineering and construction surveys for the construction of facilities on the site.
The plans shall note:
- Hydrography (water bodies. Plans depicting large areas of terrain do not indicate small water bodies);
- soil and vegetation;
- terrain;
- transportation interchange;
- engineering networks (including underground communications);
- structures (with indication of storeys and height characteristics);
- site boundaries (lands, gardens, forests, fields, etc.).
In the overwhelming number of cases, topoplanes are created at a scale of 1:500 and 1:1000, which ensures high accuracy and detail. The most accurate are sub-tree plans and landscape survey, executed at a scale of 1:100 and 1:200. (vegetation; detailed relief; hydrographic elements; buildings and structures; anthropogenic changes in the earth's crust are displayed).
It is only through a topographic plan that designs for complex structures are created. Whether it is a power line, a transportation highway, a residential building or an industrial facility. All structures occupying a significant area are built on the basis of a topographic plan of the land plot.
Electronic formats are stored forever (The electronic version is created in a specialized program and given to you on a storage medium. In special cases, volumetric 3D models are projected). But any topographic plan is valid for three years, then you will have to rescan the area.
Construction projects are currently created only in electronic format and, if necessary, transferred to paper. Computerized schematics are more accurate and visually convey all the characteristics of the site.
Pay attention to the companies that use their equipment. It is they who will be able to make an accurate plan of the land plot with all its boundaries and construction objects.
Surveying is done using geodetic equipment, total stations, GLONASS/GPS equipment. Thanks to this it is possible to obtain certain results of measurements of the plane of the site. Therefore, even in conditions of high dustiness, humidity, it provides accurate measurements
- Customer's passport.
- Terms of reference. If possible, it specifies all wishes and nuances.
- Contract on the lease of the land plot or extract from the USRN.
- Made plans (if any).
The preparation of the plan and other documents for a building permit is better to make out in one organization, since another will not take responsibility for incorrectly prepared documents.
are drawn up mainly at a scale of 1:500 and include underground utilities. More than others requires approvals, stamps and accreditations
It is depicted in the form of horizontals. Those relief elements, which cannot be shown by horizontal lines, are marked by means of special conventional signs.
For private needs and single-storey construction, the plan is not obligatory, but it will be useful when registering land for lease or ownership.
Topoplan can also be prepared independently, but only for your own use. In the case of tasks, where the scheme is included in the documentation package, it should be prepared only by surveyors, as a self-prepared document will not have legal force.
Before starting field work, geodesists are engaged in checking the available materials. After that, geodesists and cadastral engineers start working on the ground: they perform a topographic survey of the object with calculation of distance, height of coordinates of turning points. The information obtained will be used in calculations.

Topographic site plan
The topographic site plan must meet certain requirements. The scale of the plan is selected based on its intended purpose. Maps with small scales do not allow for the detailed representation of individual objects. For construction purposes, plans with scales of 1:500 or 1:1000 are commonly used. The document may include not only the scheme of the site but also additional images.
Objects and Features Depicted on the Plan Using Conventional Symbols:
- Relief: Represented by contours. Elements of relief that cannot be shown by contours are marked using special conventional symbols.
- Landmarks: Objects that can be used as reference points. They are depicted with non-scale symbols and precisely linked to coordinates.
- Transportation Network: Detailed representation using conventional symbols for various types of roads.
- Hydrography: Large lakes, swamps, rivers, and other water bodies are displayed on topographic plans with names, depths, etc.
- Soil-Vegetation Cover: Represented by specific non-scale symbols and colors.
- Engineering Communications: Both above-ground and underground communication lines are indicated on topographic plans.
The topographic site plan can be presented in various formats:
- On paper. This is the standard format and is often required for various approvals.
- In digital format. It can be a digital terrain model or a topographic plan in PDF format. The plan is certified with an electronic-digital signature.
Types of Engineering Topographic Plans
Depending on the level of detail in the representation, topographic maps are divided into several types:- Geodetic Base
- Horizontal Survey Plan
- Tree Survey Plan
The process of creating a topographic plan includes the following stages:
- Preparation of Technical Task (Geodesists prepare cartographic materials based on the Technical Task. The Technical Task for topographic survey is the primary foundational document that initiates the formation of contractual obligations between the parties. In case of any disagreements, all disputes and settlements will be based on this approved and signed document. It is crucial to consider all important details in the Technical Task; otherwise, oral agreements may simply be disregarded.)
- Contract
- Preparation
- Fieldwork
- Deskwork
- Approval
Land surveying includes a whole complex of geodetic works, collection and study of documents, the process of boundary coordination, preparation of boundary surveying file, cadastral registration and obtaining documents for registration of ownership rights.
Surveying is a geodetic method of measuring the boundaries of a land plot in the horizontal plane. In short, it is the determination of the boundaries of a land plot and their legal registration.
This type of plan is carried out to determine the boundaries of plots and objects located on the surveyed territory. It also calculates the areas of land plots and considers their mutual arrangement.
The peculiarity of horizontal survey - Usually, such a scheme does not contain information about the relief and heights. It is necessary for land division, accounting for land plots, etc. Such plans are in demand when dividing land in cottage cooperatives or determining the sizes of undeveloped land.
Clarification of the boundaries of the land plot are certain geodetic works, which are associated with the definition of the coordinates of such a plot, its dimensions, also features, then all these parameters are agreed with the neighbors.
