In this paper, I take a closer look at what data is used -- and how it is used -- in this analysis and ask if a more detailed, literature-informed GIS analysis could improve the metrics used to select the most impactful neighborhood projects. To answer this question, I analyzed the application of quantitative criteria to create a school travel plan in Kent (Ohio) City School District as well as the guidelines that explain how these data are used to make funding decisions. I then created new maps that use similar data but change the methodology by following best practices for identifying walkability and traffic issues. My analysis indicates that a more nuanced GIS analysis can identify the most impactful projects better than the maps created by the current mapping approach used in the Ohio SRTS program.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"180 ","pages":"Article 103670"},"PeriodicalIF":4.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we developed a new approach that integrates the biophysical and socio-economical perspectives for urban boundaries mapping, and tested the approach in mainland of China. First, we divided the study area into 1 × 1 km grids, some of which were classified into urban and rural based on Points of Interest (POIs) and official urban-rural classification. The classified grids were then served as training samples to determine thresholds of impervious surface percentage (ISP) for further urban-rural separation. Combined threshold of ISP (biophysical properties) with connectivity to administrative urban centers (socio-economical properties), the unclassified grids were assigned as either urban or rural. Finally, all urban grids were merged to create China's urban boundary (CUB). The integrative approach improved the accuracy of town mapping and village mapping by 15 % and 17 % respectively, compared with existing urban boundary products. Our approach is thus capable to improve mapping accuracy and provide urban boundary for social-ecological studies in urban-rural areas.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"180 ","pages":"Article 103665"},"PeriodicalIF":4.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by proposing a multi-scalar framework that distinguishes metropolitan-scale effects, shapes urban structure, and establishes regional competitive advantages from local-scale amenities, whose availability and diversity drive placemaking. Using Wuhan's automotive industry as a case study, detailed firm-level data, comprehensive amenity information, and spatial econometric techniques were employed. Findings reveal that while automotive firms cluster near high-amenity urban sectors, local urban areas exhibit specialized industrial clusters. The regression results confirm that localized attractiveness is driven by both the availability and diversity of amenities, as well as the division of urban spatial structure. However, high availability is particularly valued for essential infrastructure and public services rather than consumer amenities. Crucially, the effects of these factors vary due to the division of urban sectors: central districts mainly leverage amenities that may form a local innovation system for specialized clustering, whereas outer areas depend more on foundational public services and functional accessibility. These differentiated, amenity-driven localization patterns underscore the necessity for context-specific urban planning strategies that meet the distinct needs of different urban sectors, thereby optimizing intra-urban industrial agglomeration and economic performance.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"180 ","pages":"Article 103659"},"PeriodicalIF":4.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, characteristic towns (Tese Xiaozhen) and Taobao towns exemplify top-down and bottom-up development pathways, respectively. These emerging towns may become critical nodes in China’s evolving urban–rural system and present opportunities for modeling human mobility. This study focuses on the spatial patterns, human mobility, and their network features of NITs within China’s urban system. Specifically, we analyzed the spatial distribution of NITs and their geographic linkages with major cities. Under hypothetical short-term mobility scenarios, interconnections within the “city–NIT” system were simulated using both the radiation model and the gravity model, followed by a comparative analysis of the two approaches. Furthermore, the radiation model outputs were used to construct a directed city–NIT network, which was subsequently evaluated using complex network indicators. Results indicated significant differences in spatial distribution between characteristic towns and Taobao towns, with the latter prominently concentrated in coastal areas. Despite differences in model assumptions, results from both models showed strong positive correlations across spatial scales, with radiation model estimates exhibiting greater regional stability. From a directed network perspective, NITs channeled short-term mobility flows, shaping sub-networks anchored by major metropolitan areas. This underscores the ongoing redefinition of China’s urban system, in which smaller nodes are capable of attracting or catalyzing short-term population movements. These findings suggest differences in adaptability between the two primary human mobility models. The findings may inform optimal planning for short-term human mobility to NITs and deepen understanding of the spatial organization and hierarchical characteristics of China’s urban system. Further, the proposed framework offers a reference for integrating emerging towns in other developing countries into existing urban systems.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"180 ","pages":"Article 103669"},"PeriodicalIF":4.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
