Terra digitalis is a peer reviewed international e-journal of maps which purpose is to provide a forum for the publication of thematic maps related to Earth Sciences and Geography, among other disciplines. It also aims to facilitate online distribution of digital cartographic works and their recognition as scientific products.


Terra Digitalis publishes the results of geoscientific research using the new geographic information technologies. The journal publishes six types of documents: A. Static maps (PDF) B. 2D Interactive Maps C. 3D Interactive Maps D. Dynamic Maps E. Spatial data collections F. Reviews of institutional OGC services

The maps may be:

a. Original and unpublished maps or spatial data. b. Reinterpretations of cartographic products or data, created or collected by the same or different authors and reported in documents that have limited circulation, were not published or were not formally edited. Such is the case of professional or postgraduate theses and internal technical reports. In this case, it is necessary to specify the cartographic contribution and the criteria used in the reinterpretation. c. Documents such as those described in the previous point, which have already been published in printed or digital format. A letter from the copyright owner authorizing a new digital publication will be required. d. Compilation of various cartographic documents or data (electronic or printed), systematically integrated into a spatial database with their relative attributes (coordinates, measurements, references, methods). e. Updated versions of maps already published in printed version by the same author or by different authors. A letter from the copyright owner authorizing a new digital publication will be required

Peer Review

The maps and their articles submitted to the journal receive a single-blind review, where the reviewers are anonymous, however, the review can be double-blind or open, if requested by the author or reviewer.


The official languages are Spanish and English and the use of both is mandatory in the title, summary and captions of figures, tables and maps.


Go directly to submit

The submitted material can consist of one or more maps accompanied by an article.


A brief article explaining the scientific relevance of the data and the methodology used for its acquisition and processing, as well as the methodology used to construct the maps. Extended articles incorporating analysis and interpretations will not be accepted and it is advisable to publish them in specialized journals, referring to the material published in this journal.

a. Format

Please send a single double-spaced word document with numbered lines, containing the manuscript, figures, tables and its corresponding captions. It is also possible to send a PDF file with the characteristics mentioned above, however an editable version (* .docx) of the article must be sent once the material is accepted for publication.

b. Structure

The general structure of the articles can include:

i. Title: The title of the manuscript must be brief, specific and informative. Must be included in English and Spanish.

ii. Authors and affiliation: The full names of all authors, followed by their affiliations (department, university, city, country) and full postal address. Include the email address of the author to whom the correspondence will be addressed.

iii. Summary: The summary should include the following information: - Objective - Design / methodology / approach - Results - Study limitations / implications - Originality / value - Findings / conclusions It should not exceed 150 words in Spanish and English. It is recommended to avoid the use of acronyms and the citation of references. The scale and area of the map should be mentioned. Include a maximum of 6 keywords in both languages at the end of each abstract.

iv. Introduction: This section should summarize the research area and provide an introduction to the topic. An overview of the map can be briefly presented.

v. Methods: The research that inspired the construction of the map should be described, as well as all specific details about the methods used to collect the data or produce the map. The description of the analysis performed should also be included. If a detailed research article is planned to be published in another journal, it should be mentioned in this section.

vi.Results: Summary of the most relevant results.

vii. Conclusions: A brief summary is expected about the conclusions that can be drawn from the work, as well as its relevance and importance.

viii. Software: A brief description of the software used to produce the map is suggested.

ix. Data: If the authors have created data and these are free of rights, it is also possible to distribute them through the journal. If this is the case, in this section, the authors should explain the structure of the data, its format and the necessary instructions for its manipulation.

x. Acknowledgments: Mention individuals or organizations that have contributed to the work. It is essential to mention the sources of funding for the study (mention the institution and project or scholarship number). Also, it is possible to mention those persons who were significantly involved in the project but are not considered as authors, such as cartographers, database managers, persons who carried out the field work, etc.

xi.Map design: At the end of the article it is possible to include a small paragraph explaining to the editor the decisions made in terms of the map design. This is not intended to be part of the final manuscript. It is important to mention that the map must be able to be understood independently of the associated article. Explanatory text related to data classification, which is imperative to understand the resulting maps, should be summarized and included as text within the map page.

xii. References: The Harvard Elsevier format is used.

xiii. Appendices: Can be included if required.

xiv. Figures and tables: Include captions of figures and tables feet Spanish and English
