“…This result will be confirmed below. Following the analysis developed by Ariza et al [52], Figure 4 shows the distribution functions by line of the general results obtained in this study. Obviously, all functions show percentages of inclusion (Y-axes in Figure 4) increasing with the displacement (X-axes in Figure 4).…”

This study describes a new method developed to determine the 3D positional displacements of the drainage networks extracted from Digital Elevation Models (DEMs). The proposed method establishes several stages for data preparation. The displacements are derived by means of linestring-based assessment methods, which can be applied in 2D and 3D. Also, we propose the use of several tools (maps, aggregation of results, new indices, etc.) in order to obtain a wider assessment of positional accuracy, or a time change analysis. This approach supposes a novelty in drainage network studies both in the application of line-based methods and its expansion to 3D data. The method has been tested using a sample of channels extracted from DEMs of two different dates of a zone of about 600 square kilometers using as reference linestrings those extracted from another more recent DEM which had higher spatial accuracy and higher spatial resolution. The results have demonstrated the viability of the method proposed because of the obtaining of 3D displacement vectors, which showed the general and particular behavior of the channels selected.

“…Nevertheless, researchers have criticized these standards for being limited to well defined points, and also for failing to address more complex elements like linear and polygon ones. It is not possible to assume that all features can be characterized by an error in the position of well-defined points [2].…”

The paper describes the visualization possibility of estimated results of horizontal positional accuracy of digital topographic map scale at 1:25 000 (DTM25) using geostatistical interpolation method. Estimation of horizontal positional accuracy DTM25 is realized by using standard STANAG 2215 (Standardization Agreement), which is intended for publishers of geotopographic material, or national mapping agencies for assessment of horizontal and vertical positional accuracy of spatial data by using ArcGIS software. The estimated results of horizontal positional accuracy are shown by means of a map that uses interpolated values of the root mean horizontal position. Rezime:U radu je opisana mogućnost vizualizacije dobijenih rezultata ocene horizontalne položajne tačnosti digitalne topografske karte razmera 1:25 000 (DTK25) korišćenjem geostatističkih metoda interpolacije. Ocena horizontalne položajne tačnosti DTK25 realizovana je na osnovu standarda STANAG 2215 (eng: Standardization Agreement), koji je namenjen izdavačima geotopografskog materijala, odnosno nacionalnim kartografskim agencijama za ocenu horizontalne i vertikalne položajne tačnosti prostornih podataka, korišćenjem softvera ArcGisfirme ESRI. Rezultati ocene horizontalne položajne tačnosti prikazani su pomoću karte sa interpolovanim vrednostima korena srednjeg horizontalnog položaja.

This article presents a positional quality acceptance control method for 2D and 3D line strings based on a statistical hypothesis test. Two statistical models are applied together: a Binomial Model is applied over a Base Model. By means of the Base Model the method can be applied to any parametric or non‐parametric error model. The Base Model represents the hypothesis about the error behavior. The Binomial Model is fixed and consists of counting the number F of fail events in a sample of a determined size. The π parameter of the Binomial Model is derived from the Base Model by means of a desired tolerance. By comparing the probabilities associated to F and π a statistical acceptance/rejection decision is achieved. This method allows us to know and control the user's and producer's risk of acceptance/rejection. An example using a 2D line string data set from a commercial product is presented. The extension of the method to the 3D line string case is also presented. In order to facilitate the application of the method, some tables linking π with F and the control sample sizes are presented.
