Abstract
This research solves the problem of navigation network construction for panoramic survey points inside courtyards without using road network information. The described method of navigation network construction takes into account a number of geometric conditions that detecting and identifying the regularities of the decisive routing rules construction. An algorithm for constructing links between panoramic shooting points, based on the surrounding area and linear objects territory information, is presented. An intelligent agent of geographic information system has been developed that executes this task based on the proposed decision rules. The goals and objectives of the research are presented, input data array to solve the problem is considered, the formulation of geometric conditions, structure and object implementation of the algorithm are set out in this work. The task is viewed in terms of the perspective of graph theory, implemented in the DBMS PostgreSQL and illustrated in the QGIS geographic information system.

Summary
Spatial routing is based on a number of geometric conditions, as well as conditions for interaction with surrounding objects. Аn intelligent agent must interact with an array of spatial data to fulfill decision rules [7]. An array of linear objects that connects the panoramic survey points from the Panoramas table. ID (integer) – the number of area object; 2. Geom (geometry) – spatial coordinates of a given area object; 1. ID (integer) – the number of line object; 2. Geom (geometry) – spatial coordinates of a given line object; 1. ID (integer) – the number of a given line object (edge); 2. Pano_1 (integer) – Panoramas.ID number of the starting point of line object; 3. Pano_2 (integer) – Panoramas.ID number of the ending point of line object; 4. Geom (geometry) – spatial coordinates of a given line object; Fig. 1.
